When I plug my 3G into itunes the iphone icon comes up but there's only Music Movies TV Shows Ringtones underneath it. Is there supposed to be an Applications section? I'm trying to transfer my apps and data from my 3G to my 3GS. When I do a backup my 3G isn't backing up my apps or my music or my ringtones or anything. It's only backing up my contacts and settings for apps like stocks and weather. Help?
