Hi, I plan to backup my current 2.2.1 iPhone 3G, reset it, pass it down to another person. Then get the 3Gs. Will it be easy to do this? I don't mind reloading the media (music, videos), but would it be easy to restore the apps? I have about 50 so far and can't weed through them again. The contacts, settings, datebook, pictures, etc is what's important.
