Ok..i already got the instructions on how to jailbreak my iphone 3g...but heres the thing. I've already have regular service through regular activation...do i jailbreak my phone WITH my sim card already in with service or is there something i have to do before then? Will i be able to get my regular service back after jailbreaking my iphone? Do i take my sim card out before jailbreaking? I'm a little confused....help is appreciated.
