1. How to sync your iOS device's app with more than one computer?
The right of the useage of app is related to Apple ID account, one account can authorize upto 5 computers. Only the authorizen computers can sync apps with your iOS devices and the apps already on your iOS devices will not be deleted. If you have more than one account, every iOS device can authorize 5 different Apple ID accounts at one time. For example, if you have an iPhone, you can sync apps you buy from 5 different Apple ID accounts at the same time.
Run iTunes and you can find "Store" on the top of the iTunes interface, authorize the computer to your Apple ID account. After you have finished this, iTunes will show "including this one, you have authorized X computers out of your available 5". X represents how many computer you have already authorized and the max is five. If the computer is public or just for a short time, you need to cancel the authorizen before you leave.
Sometimes, you could just change computer all the time or you always use different computers and you have already authorized 5 computers and you must authorize a new computer right now. But you can not cancel other computer. Don't warry, you can use iTunes to cancel the 5 authorized computer with your Apple ID account.
After you have finish the authorizen, you can sync your iOS device with apps from different computer. (This time we only talk about app, but not music, video, and other media files.)
Step 1. First you need to connect your device to your computer and do not sync at once. If there is no iOS apps on this computer, the sync will be cancelled after you finish it. So it is necessary to have apps on your computer. The most fast way to do that is to transfer the apps from your iOS devices to your computer. Here you need to right click and choose sync purchased app.
Step 2. Then you need to go to "app" page and check the apps you want to sync. There will be a pop-up note from iTune, you need to choose "sync app". That's it. If you want to sync apps with different computers, remeber you need to transfer the purchased apps to the computer and then you can sync your apps. itunes customer service.
