3G iPad 2- Change SIM on the fly

Hi folks,
Can one switch the sim card for that of another provider without needing to connect to iTunes or is there some registration process that goes on that requires us to connect the iPad to iTunes before activating and purchasing a plan? I'm presently with Rogers and would like to try Bell Canada to see if I can get a stronger signal.
Thanks in advance

Should have checked the boards better as the following answer by OrangeMartin indicates that swapping sim cards on the fly is doable.

TS1398 My ipad says NO SIM in the top left corner

My ipad says NO SIM in the top left corner instead of ATT like it used to.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430http://support.apple.com/kb/ht1430

Why does my iPad say " No SIM " in the upper left corner ?

Hi Edwardtracey,
Welcome to the Support Communities!
It sounds like you have a cellular data plan and there is no service where you currently are.
The article below will explain this feature and how to turn the setting on/off.
The article has more details and screenshots, but I've quoted highlights below for you:
iOS: About the Cellular Data setting
Cellular data is used for data communication in cellular networks. It does not affect your ability to make or receive phone calls or to use Wi-Fi networks for Internet connectivity. If you turn off cellular data, you will be unable to:
See the cellular data icons in the status bar (for example, LTE or 3G).
Send or receive MMS messages. However, you can still send and receive SMS and iMessages if you're connected to a Wi-Fi network.
Retrieve or listen to new Visual Voicemail messages. To retrieve these messages, enable Cellular Data.
Use Personal Hotspot.
You can adjust this setting by going to:
iPad: Settings > Cellular
Additional Information
You can also enable or disable cellular data for certain iOS features from this setting:
I hope this information helps ....
Have a great day!

Best way to change GUI on the fly

Scenario :
A program has a simple GUI, subclassing JFrame with a JPanel content pane. Initially the GUI is a simple few text fields and a JButton. Now for the part that eludes me, when the JButton is clicked the GUI should be replaced by a graph drawn from information in the text fields.
Coding a custom subclass of JComponent to handle the graphing is not a problem but the step to remove the text fields and JButton eludes me. What options are there and what pro/cons do they have?
Cheers

when you update layouts in any way, you need to call the container of the GUI's validate() method. this will ensure everything is where it needs to be. to change your gui over to your graph, it's a good idea to remove eevrything from the current GUI, add the graph, and then call the validate method. I'm really bored so I wrote you a simple example:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Graph extends JPanel {
     int y[]; // y-axis (inputted)
     int x[]; // x-axis (computed)
     public Graph(int y[]) {
          this.y = y;
          x = new int[y.length];
          setBackground(Color.white);
     public void paintComponent(Graphics g) {
          super.paintComponent(g);
          int n = 0;
          for (int j = 0;j < x.length;j++) {
               x[j] = n;
               n+=(getWidth()/x.length);
          g.setColor(Color.blue);
          g.drawPolyline(x,y,x.length);
public class Example extends JFrame implements ActionListener {
     JTextField text[]; // input fields
     JButton button;
     JLabel label[];
     public Example() {
          super("Example");
          Container c = getContentPane();
          c.setLayout(new GridLayout(0,2));
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          text = new JTextField[10];
          label = new JLabel[text.length];
          // below is default GUI setup
          for (int j = 0;j < text.length;j++) {
               label[j] = new JLabel("Y value #"+(j+1)+": ");
               text[j] = new JTextField();
               c.add(label[j]);
               c.add(text[j]);
          button = new JButton("Graph!");
          c.add(button);
          button.addActionListener(this);
          pack();
          setSize(new Dimension(400,getHeight()));
          show();
     public void actionPerformed(ActionEvent e) {
          if (e.getSource() == button) {
               int j;
               int y[] = new int[text.length];
               for (j = 0;j < y.length;j++) {
                    try {
                         y[j] = Integer.parseInt(text[j].getText());
                    catch (NumberFormatException ne) {
                         // one of the fields isnt an
                         // acceptable number, so forget about it
                         return;
               // here the GUI needs to be rebuilt
               Container c = getContentPane();
               for (j = 0;j < text.length;j++) {

               c.setLayout(new BorderLayout());

Change CharPalette on the fly

Hello
As it seems that the favourite page of the CharPalette may help many of us, I wrote a couple of scripts allowing us to switch from a page to an other one.
It is fine also to instal a specific palette on several machines.
The beast is available in my iDisk.
<http://idisk.mac.com/koenigyvan-Public?view=web>
Download: koenigyvan:Public:change_palette.dmg.zip
Unpack it will give a dmg file named "change_palette.dmg".
Open it will give you a disk image on the desktop.
Double click on "grab_palette.applescript" will open the 1st script in the Script Editor.
Execute it.
You will be asked to create a folder in the disk image then, the installed palette definition will be copied into the new folder.
Double click on "install_palette.applescript" will open the 2nd script in the Script Editor.
Execute it.
You will be asked to choose a folder containing a palette definition in the disk image then, the palette enclosed in the selected folder will be installed in your account.
Play with it, it's FREE and efficient.
I left the script in text format because I don't own a MacIntel and so I am unable to check the behaviour of scripts compiled as bundles on these machines.

You can print the very first page on a letterhead and the rest on plain paper, not sure if it can be done where the first page of every group is printed on a letterhead.
File | Print | Preferences
Depending on your printer, under the 'Paper' tab, you should see a tab titled 'All Pages'. Under it you should have a check box with 'Use different paper for first page'. Upon checking that box, you will be given options on which tray and paper to use for the first page and the same for the other pages and also for the last page.
That is how I print the first page on letterhead and the rest on plain paper. The only issue I see with your printing would be to get it to print on letterhead for every group header.

JAVA 3D: How to animate "on-the-fly"?

Hy guys,
I'm new to Java 3D and I've read a whole bunch of tutorials as well as Selman's book.
However, as great as Java 3D seems, it seems like I can't get Interpolators to work the way I want them to! Here is my goal:
Create a simulation where the View is FIXED and the main ANIMATED character (comibnation of objects) MOVE AROUND the universe through the user's keyboard commands.
I've managed the above by creating all my objects, adding them to a branchgroup, adding that branchgroup to a transformgroup, adding a few interpolator animations to the transformgroup and finally adding a cutom keyboard navigator behavior to the transformgroup.
The following problem has occurred:
I can't NICELY move the transformgroup around because I use Transform3D objects to calculate the next position of the transformgroup and I then apply it to the transformgroup by calling the "setTransform" method on that group with the Transform3D object. The result is an instantaneous leap x locale units away with no animation in between the original and final position. :o( This is the only way I got this working. The Java runtime keeps yelling at me that I can't add or remove Interpolators or transformgroups from other transformgroups or branchgroups, so I can't change interpolators on-the-fly (say, when the user wants to move in a different direction)... Can it possibly be that we can only declare and use interpolators at prior to executing a universe?!
The IDEAL solution I'm looking for (!INSERT YOUR HELP HERE! ;o) ):
Replace the ugly "setTransform" call by adding a PositionInterpolator or something to the transformgroup object in order to generate a SMOOTH ANIMATION from the original position to the final position. The end result will be must nicer and more professional.

Ok, I've modified the simple behavior class in order to extend the PositionInterpolator class and be able to get a translation that always begins from the last target position. Eventually, I'd also like to be able to modify the AXIS so I can change direction... Anyway, right now I just want what IWON managed to do in one direction.
Here's what I got that DOESN'T WORK, can someone please help me, IWON?:
// Allows an object or group of objects to be moved around SMOOTHLY by the keyboard.
public class KeyboardControlBehavior extends PositionInterpolator {
private TransformGroup source;
public static final float distance = 0.1f;
public static final long time = 200;
// create SimpleBehavior
KeyboardControlBehavior(TransformGroup source, TransformGroup target){
super(new Alpha(1, Alpha.INCREASING_ENABLE, 0000, 0, time, 0, time, 0, 0, 0), target);
// initialize the Behavior
// set initial wakeup condition
// called when behavior beacomes live
public void initialize(){
// set initial wakeup condition
this.wakeupOn(new WakeupOnAWTEvent(KeyEvent.KEY_PRESSED));
// behave
// called by Java 3D when appropriate stimulus occures
public void processStimulus(Enumeration criteria){
// Check which direction we're going and adjust the AXIS and endPosition
// in consequence.
KeyEvent event = (KeyEvent) ((WakeupOnAWTEvent) criteria.nextElement()).getAWTEvent()[0];
int c = event.getKeyCode();
System.out.println("KEY PRESSED = "+c);
if ( c != KeyEvent.CHAR_UNDEFINED ) {
if(c == KeyEvent.VK_UP) {
System.out.println("UP");
if(c == KeyEvent.VK_DOWN) {
System.out.println("DOWN");
if(c == KeyEvent.VK_LEFT) {
System.out.println("LEFT");
if(c == KeyEvent.VK_RIGHT) {
System.out.println("RIGHT");
// Let the PositionInterpolator animate the translation.
super.processStimulus(criteria);
// Adjust the source's position to be at the end position of the
// animation (same as target).
Transform3D newPosition = new Transform3D();
Transform3D oldPosition = new Transform3D();
source.getTransform(oldPosition);
target.getTransform(newPosition);
newPosition.mul(oldPosition);
source.setTransform(newPosition);
// Reset the Alpha class since it only executes once.
super.getAlpha().setStartTime(0);
// Consume the event.
event.consume();
// do what is necessary
this.wakeupOn(new WakeupOnAWTEvent(KeyEvent.KEY_PRESSED));
} // end of class SimpleBehavior

My iPad (4th gen) is stuck in one orientation. It will change if locked, rotated, and unlocked, but not on the fly. I have tried restarting multiple times.

I have a fourth gen iPad that's a few weeks old. It is stuck in whichever orientation I unlock it in, and will not rotate on the fly.
I've tried restarting multiple times. I've tried toggling the side-switch to screenlock or mute, on/off, with no success. Tried closing all programs. Tried locking via software and unlocking...
Still no luck. Any suggestions?
Thanks,
M

Sounds like a hardware failure. Make an appointment at the genius bar of your local Apple Store. There is no magic that can fix a hardware failure.

If the SIM is out of your phone, find my phone needs a data connection, so could use wifi - IF in range of a wifi and one that it can join (ie. a known network or one that is wholly open so no login required). Your phone could also simple be turned off, so not findable, or it may have been restored (plugged into iTunes and restored as new) again, making it permanently unfindable. Honestly, for someone stealing an iPhone, this is likely the first thing they do - restore as new and it is theirs forever.
Find my iPhone is tied to the users iCloud account - the find function is part of the iCloud account's services and it communicates with the iCloud servers over a data connection - either wifi or 3G.
Have you set up your iCloud account on your replacement phone, and is it working properly on that phone?

I can not view ANY videos on Vimeo, I have 'reset' the Ipad, original IOS 5, cleared the history and cookies, I have changed the DNS number to 8.8.8.8, I have worked on this for 2 days and still can't find a fix, HELP!!

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.

I want to use the Function Generator VI to send command signals through the NI 7344 motion controller. This will be a closed loop servo valve system. I want to be able to change from say a square wave to a sine wave on the fly. Idea's?

I am going to run tests that require an actuator to move using various types of arbitrary waveforms such as sine or square. The NI 7344 is hooked to the UMI that is going through a driver for a servo valve. The loop is analog and it is closed. I have played with some of the examples but can't get it to work. I have used the function generator VI to generate a signal but I think I am using the wrong input VI to the motion control board. When I use what I have it moves the servo and then stops. It doesn't continually generate the signal.
I would love to use the controls on the function generator vi to control frequency and amplitude ect. Any help or pointer would be helpful. Thank you in advance.

Hello,
I'm not clear on exactly how you want to use the generated data but I'm assuming they will be used as your target points.
There's a built-in example for motion called 'One-Axis Contour Move.vi'. This example demonstrates how to provide your target points as 1-D array. All you need to do is to replace the input array with the output of the function generator. In order to have it run continuously, use a while loop. You can further program your application so that it'll change the waveform on the fly by monitoring the user interface but this might be little little tricky as you will need to reset the move and load the new generated points while keeping track of your current position.
I hope this helps. Let me know if you have further questions regarding this
application.
Best regards,

I have two iPhones and an iPad under same Apple ID. How can I change one of the iPhones to a separate id?

I have 2 iPhones & an iPad under 1 Apple ID. How can I change 1 of the iPhones to a separate account?

Sign out of the Apple ID on the device in question, making sure to disable the Find My iDevice feature.
Sign in with the new Apple ID.
If the intent is to sell the device, simply restore as new after disabling the Find My iDevice and signing out.

Ipad and Iphone with different apple ID. Changed to same, but can't change the Ipad Icloud to match with the same @me account. Help!

When I got my Iphone, I couldn't remember the apple ID, so Best Buy created one. Now my Ipad Icloud account has a different ID than my Iphone. Can I change this so all the passwords match? I was able to log in to the Ipad and change the Apple ID to match the Iphone but can't find a way to do same for Icloud on Ipad.
thanks

So are you trying to change your passwords? Or change which account is logged into icloud?
Here are the instructions for changing which account is logged into icloud. Go to settings-icloud-delete account. Then settings-icloud-sign in with the account you wish to use.

Hope you can help.
I have added a new email address but kept my Id, but I get busy when trying from iPhone to iPad as they are clashing. Like find my iPhone app hence trying to keep them all on one account

IOS: using facetime http://support.apple.com/kb/ht4319
using an ipad will use the email address since you can't make a phone call. see the link.
Your basically calling/emailing yourself that's why your getting a busy signal.
