Help? Looking to buy 30 old ipods for an art project? here are the pictures of them. Anyone know where to get?
Hi, I am wondering if anyone can tell me where to get a bunch of these?
That's not the original iPod as stevejobsfan0123 said.
That's the Third Generation iPod with Touch Wheel
is this one.
Anyway, you should be able to find them on eBay, they are quite old (2002-2003), so you should be able to get it for little money.

I have an iphone 5 and ipad. I paid for icloud. I "think" iphone is okay but ipad keep saying can't verify account. I can't change that. I have been sent to the page on apple about setting up icloud but that doesn't help. There is no place for me to fix my account or change anything. Anyone know what to do? The apple support page doesn't answer my question. If just has instructions to set up, but I can't get anywhere on the ipad since it keeps telling me account not verified.
Welcome to the Apple community.
This feature has been introduced to make stolen phones useless to those that have stolen them.
However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7.
The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID verify the changes, enter the password as requested on your device and then turn off "find my phone".
You should then change your Apple ID back to its current state, verify it once again, delete the iCloud account from your device and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again. -
Please Please Help with Projectile Project Here are the Codes
I've got three(3) classes a Model, a view, and a controller.
This is a project about projectiles.it is an animation of a cannonball being fired from a cannon and travelling under the effect of gravity.A cannon fired at angle 'a' to the horizontal and with an initial speed 's', will have an initial velocity given by:
vx := s * cos(a);//velocity x equals the speed multiply by the cosine of angle a.
vy := s * sin(a);//velocity y equals the speed multiply by the sine of angle a.
Here are the code.

if the cannon ball land in the bucket it should stop and the animation should indicate a 'hit' in some way. maybe by displaying a message.
if the cannonball hits the outside of the bucket it should bounce off.
Extra Notes.
1) The acceleration due to gravity is 9.8m/s to the (power of (2) eg s2.
2) The distance travelled in time t by a body with initial velocity v under constant acceleration a is:
v * t + a * t.pow(2) div 2;
The velocity at the end of time t will be v + a * t.
Distance is measure in pixels rather than meter so for simplicity we use 1 pixel per meter
When i pressed the fire button nothings happens. I'm going crazy. Please please help!Here is the interface specification for the RotatablePolygon class. I do not have the actual .java source.

if the cannon ball land in the bucket it should stop and the animation should indicate a 'hit' in some way. maybe by displaying a message.
if the cannonball hits the outside of the bucket it should bounce off.
Extra Notes.
1) The acceleration due to gravity is 9.8m/s to the (power of (2) eg s2.
2) The distance travelled in time t by a body with initial velocity v under constant acceleration a is:
v * t + a * t.pow(2) div 2;
The velocity at the end of time t will be v + a * t.
Distance is measure in pixels rather than meter so for simplicity we use 1 pixel per meter
When i pressed the fire button nothings happens. I'm going crazy. Please please help!Hi,
U put something on forum and keeping silence.If it is not necessary dont put in forum.I moved your cannon ball.If u want continous movement I need some more information.

I need to install the ipod software that did not come with my nano. Tech support ended 7 days ago. Does anyone know where I can get the software?
Thanks, KWhich generation Nano and what software are you referring to? There are no downloadable apps on a Nano.

Just wondering. Don't want one with anything other than music capabilities.
Just do a google search. There are a ton of websites that sell refurbished ipods for very reasonable prices. You could also try craigslist or your local classifieds.

Hi everyone. My voicemail just stopped working. A caller today said they got a message that it was not activated or something like that. When I called it from another phone all I got was ringing for a long time and then a disconnect. I have had this phone for about three months and it has been working until now.
I updated software and turned the phone off and on again. Any other suggestions? Thanks.

I know this email is confusing and really hard to understand...perhaps now you will know how i've been feeling--lost and confused with all the mis-information, with a hit and miss phone, and out of time with all the 1 1/2 hr to 2 hrs EACH wasted on this issue.
On top of all this, I can't even find out how to file a complaint with anyone higher up than Customer Service.
I hate to tell you this, but you didn't write an email. You wrote a discussion post on the Verizon Wireless Community forum which is a public peer to peer forum. Unfortunately since you didn't mark your post as a question, the VZW reps that roam this community won't ever see your post. Before you re-post it, don't. Duplicate posts get removed from the community.
I see there were several missteps both by the reps and yourself in your post. First you should have insisted on returning the phone within the 14 day return policy period. Second which Samsung Galaxy mini model did you purchase? The S3 mini or the S4 mini? Did you do any research prior to deciding on this device. The reps at that time deflected the easiest course of action, by trying to get you to replace the phone under insurance instead of returning the phone. The Early Edge payment option requires the current phone on the line using the early Edge must be returned to Verizon Wireless. Did you once considered going to a third party site like Swappa to purchase a gently used device for your daughter? -
I have lessons created using Captivate that my high school students use. I would like the student taking the test to type their name and have it appear on the score page so that they cannot share results.
Otherwise kids can do these for HW and share it with their friends.
thanksSupposing you don't use a LMS, this could be the work flow:
Add a Text Entry Box in the beginning of the course to ask for the name. If you want to be sure that they really do enter a name, have a look at:
Where is Null? - Captivate blog
Each Text Entry Box has an associated user variable.It is created automatically with the same generic name as the TEB, but you could better use a more significant name for the user variable:
Save Time: Create Associated Variable for Text Entry Box while Defining this TEB - Captivate blog
On the Score slide, insert a text container (caption or shape) in which you insert the user variable, using the X button in the Properties panel of the text container; it will appear between $$ and be replaced by the value of the variable on runtime -
This driver does not appear in the apple search list.
Any ideas on where i can locate a driver.Try the HP site. Apple's drivers come from the printer vendors.
Don't be all that surprised if there isn't an updated driver available; HP don't support superceded models with updates for every OS update. -
After updating to FCPX 10.1.1 my shape mask starts waaaay off screen. Too far for me even to grab the center fully zoomed out. My friends mac had the same problem after the update. Anyone have an idea on what to do? Thanks
Make an appointment at the genius bar of your local Qpple Store. An out of warranty replacement will cost you $269.

If you are sure that your password is correct try restarting your router by removing power to it for 30 seconds and restarting. On your iPod go to Settings > General > Reset > Reset network settings. Now try to connect.
