well it depends if you're getting the apps from the appstore or on your computer, if you are syncing from your iphone then u should try to sync from your computer and if that doesnt work then maybe take it back to the store and ask the experts...hope it helped!
Sync your iPhone to iTunes on our computer
Click on the IPod symbol, when you plug it in, on itunes. Up top go to "Apps" and select "Sync Apps" off to not sync them :)
no, the sync just transfer the apps you have downloaded to the computer
If the applications are downloaded via iTunes, they will be automatically transfered to the iPhone during synchronization. Otherwise, the apps downloaded via iPhone will be copied and backed up to the iTunes during synchronization. So to transfer the apps to the iPhone, just connect the phone to the iTunes and sync. Click on iphone on the side bar, then apps up the top, then sync apps.
itunes will back up your apps when you sync your iPhone if the computer is authorized (store-authorize computer in itunes).
Connect your iPhone/Pod to your computer/laptop, open iTunes and sync your iPhone/Pod. The apps will then appear in your "applications" tab of iTunes.
As long as your computer has itunes that is authorised on the same itunes account as your iphone, then it will automatically transfer all your iphone apps onto the computer
iTunes will handle both your iPhones separately without mixing apps up.
If you have already purchased apps while online with your iPhone or Touch, open iTunes with your device connected, go to File > Transfer Purchases From "your iPod."To sync apps bought with another account, go to Store > Authorize Computer, and enter the username and password used to purchase those apps. Note that you can only authorize 5 computers with your account, so choose wisely.
You download the app and then sync the itouch or iphone to your computer. Warning: You can not download apps on anything but an itouch or iphone.
Connect your iPhone to your computer and sync it with iTunes...
Firstly you have to get an apple ID. Now go to the app store and get the apps you would like on your IPhone. Then you get the cord and connect it to your computer. Then go and sync your Iphone. Or you could just get it off the app store on your IPhone.
