Hi Venkata from NZ,
If you are having an issue with the speaker on your iPhone, I would suggest that you troubleshoot using the steps in this article -
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support
Thanks for using Apple Support Communities.
Best,

I received telling me that my icloud storage is almost full. I need to upgrade my storage. Can someone help me out with this. I understand that the 20 GB is only .99 per month. Just hoping this would be enough for me. I back up 2 ipads and my iphone on the same computer. Any help you can give me would be appreciated. Thank you.
Okay.
I responded as I did because you wrote, "I have 2 ipads and my iphone that I back up on one computer"
No worries here.
But hopefully you get/got it sorted.
Any issues, post back. -
I just got the iPhone 5. It's completely synced and working. All my contacts are loaded. However, caller ID is not working when I receive a call or a text. Can anyone help me out with this?
Well, assuming all of the above, Notifications, etc., it just might be time for a visit to the Apple tore genius center for a session with the techs. See if it is a fault in the hardware or just an iOS reinstall is the answer.
One more thing you could try, backup so you have a record of content, then restore to factory conditions be an Erase All Contents and Settings. Then restore from the backup you just made. That has helped some with WiFi problems, may be it would work with your problems.
But with that behavior of another app with problems, the geniuses looks like a less stressful thing to do. -
I have a macbook Pro i7 mid november 2010. I am wondering if i can exchange my notebook with the latest one. Can anyone help me out with this query please.
You can sell your existing computer using eBay, Craigslist or the venue of your choice. You could then use the proceeds to purchase a new computer.

I have Windows 7 home premium, running on a Dell XPS 15, with 64 bit OS, and when i went to install itunes for my new phone, it would almost install, but then say that it couldn't install due to issues with windows Installer. has anybody had this happen to them? can anybody help me out with this?
Many thanks.
"There is a problem with this Windows Installer Package. A program required for this install to complete could not be run. Contact your support personnel or package vendor".
Perhaps let's first try updating your Apple Software Update.
Launch Apple Software Update ("Start > All Programs > Apple Software Update"). Does it launch and offer you a newer version of Apple Software Update? If so, choose to install just that update to Apple Software Update. (Deselect any other software offered at the same time.)
If the ASU update goes through okay, try another iTunes install. Does it go through without the errors this time? -

Kindly help me out with this prepared statement
Hi All,
I am having some problem with this code.The databaseUsername and databasePassword seem to be printing only null, what could be the problem.
AFIAK, it is not going into the while loop itself.
Help would be greatly appreciated.
TIA
AS
try {
String sql = "SELECT username, password FROM admintable WHERE username = ? AND password = ?";
PreparedStatement stmt = null;
ResultSet rs = null;
stmt=con.prepareStatement(sql);
stmt.setString(1, username);
stmt.setString(2, password);
rs = stmt.executeQuery();
String databaseUsername = null;
String databasePassword = null;
while (rs.next()){
databaseUsername=rs.getString("username");
databasePassword=rs.getString("password");
System.out.println("Values are Username " + databaseUsername);
System.out.println("Values are Password "+ databasePassword);
rs.close();
stmt.close();Hi Again,
I would like to tell that there is only one entry in the database table.
String sql = "SELECT username, password FROM professorforminfo.admintable WHERE username = ? AND password = ?";
PreparedStatement stmt = null;
ResultSet rs = null;
stmt=con.prepareStatement(sql);
stmt.setString(1, username);
stmt.setString(2, password);
rs = stmt.executeQuery();
String databaseUsername = null;
String databasePassword = null;
while (rs.next()){
databaseUsername=rs.getString("username");
databasePassword=rs.getString("password");
System.out.println("Username value " + databaseUsername);
System.out.println("Password value "+ databasePassword);
}catch(SQLException sqlEx){
System.err.println("Unable to connect to DB");
sqlEx.printStackTrace();
rs.close();
stmt.close();Why do you think that the databaseUsername and databasePassword has null values in them.
Kindly help me out.
Thanking you

Could anyone help me out with this please?
Hi all,
I have always had a little problem messing with gradients, when creating images using them I tend to try and make things to perfect and then get very frustrated. This is the case again today
I have attached two images, one light and one darker. Could anyone help me out recreating these using FW please?
I am not after the letters in the center, I am just trying to create the background and the floor of the image with all its gradients and shadows.
Any help greatly appreciatedNo I don't, never heard of that

My Ipod doesn't sync songs anymore, can anybody help me out with this?
Hi all. Yesterday i did a Recovery on my computer and that wiped everything clean off of my computer, including the Itune program that i downloaded. And now, every since i downloaded Itunes again, it won't sync songs into my Ipod anymore. When i would download a few songs into Itunes, I would press on the sync button a message comes up saying that my ipod is synced with another Itunes library and can only be synced with one at a time. This won't let me transfer the songs onto my ipod. When i tryed to sync my songs again another message pops up saying to 'erase and sync'. Meaning that in order for me to sync the new songs onto my ipod, then they are gonna erase all of my existing songs that is currently on my ipod already! I don't wanna do that. I thought about restoring my ipod but i'm afraid that that would erase all of my songs off of my ipod as well. What do i do? Help would really be appreciated. Thank you.
Your iPod is designed to sync with only one iTunes library at a time. It will recognize the iTunes library on the restored/rolled back PC as a new library. If you sync the iPod with this new/different library, all content will be erased from the iPod and replaced with what is in the new library. So what you will want to do is copy everything from the iPod to your new iTunes library on your PC first.
See this older post from another forum member Zevoneer covering the different methods and software available to assist you with the task of copying content from your iPod back to your PC and into iTunes.

I need some help with the GUI design.
Have you tried the line inputs on the back of your FirePod? If you update its firmware (not sure if you will need to or not), I seem to remember hearing that the FirePod can run without FW connection, i.e. stand alone. In this mode with the outs from your mixer into line ins 1-2 (2nd from left on the back) it should work fine. I say should because I have never tried. However, these are used for returns from an external effects unit. I assume here, and the important word is assume, that there are two so that they can be used as a stereo send or as a mono send. Worth a try! Let us know how it goes.
Best, Fred -
