Hey guys bear with me as theres an influx of noob questions i'm adding to the fire. I have a 3gs right now and i'll be upgrading to the 4. I wanted to know when i activate it via itunes when i get it does all my apps, contacts, etc sync to the 4 as soon as i plug it in or is there something special i have to do. And once i do sync everything to the 4 what happens with my old 3gs as far as all my contact info apps installed, email addresses saved etc. Reason i ask is cause i'm selling my 3gs to a friend and i wanna make sure all the apps i bought and have is transferred to the iphone4 and my old 3gs is wiped clean.
