i have noticed that when i sync my iphone 4G to my PC my apps do not sync to my PC or vice versa. When I click on my iphone icon in itunes and choose the apps tab i am given the option of syncing apps but i am given the warning that the apps on my iphone will be deleted and the apps in the itunes library will be synced. but almost all of my apps have been purchased on my iphone and i would stand to loose quite a lot. there are, however, a few apps that i have purchased/downloaded on my PC that i would like to sync/transfer to my iphone. what am i doing wrong? i don't remember having this issue in the beginning. i have ios 4.1 installed. i would appreciate any help, direction, or advice. thank you.
