Im thinking to restore my iphone 3g and dont want to lose my apps.
Then when I do restore it, how do I sync it back?

does anyone know?
okay, so i just got an iphone, and ive never had an itunes account before, and i let this dude at my school use his itunes account info to download apps, and now, its defaulted to his e-mail and stuff, and i am wondering how to change it to a different one.

I had to re download itunes because my computer got messed up, and i have all my music and apps and everything still on my iphone and i havent synced it yet
i got all of my music back into itunes, but how do i get my apps back into itunes? because once i sync it i think that it will delete all of the apps from the iphone…how do i get them back?

i jailbroke my iphone and all the stuff and im using intallous been gided by youtube and it says sync craked apps with ituned what does that mean??? what does it do?

1) Can cracked iphone apps downloaded through Installous be synced to itunes, then synced again to a non-jailbroken iphone/a previously
jailbroken iphone that has been restored to factory settings?
2) If possible, do you need anything such as miPatch and what exactly does miPatch do?
