hmm thats weird hmm i just try’d to delete an app on my computer them sync my touch and yup it deleted it i thought it would just transfer the app on to my computer like it does with my apps i got from the itouch app store cause i have Manually Manage option on but nope it just deleted off my itouch so
OH! i found out how to get them back with my idea when you plug in your touch right click on it and click transfer purchases and when i did that it transferred the app i deleted on my computer back to the computer

if you reconnect to your computer, i think it transfers purchased items such as apps, bought music and videos and such, and if im wrong then theres a box that comes up when you plug in an ipod thats synced with another library and theres a cancel, erase everything, and transfer button.
