First off, I am on AT&T using a 2G iPhone that was given to me that I jailbroke and unlocked, so I am not paying for the data plan. I am using a sim card that is about 5 years old and not a 3G sim card.
My questions are:
1. If my friend sells/gives me his phone if a new one comes out in the summer, can I use my old sim card in the 3G phone? I do not receive 3G in my area, so I wouldn't be missing out on any speed by not having a 3G card.
2. He has updated the latest software to 2.2.1 so it is not currently unlockable, just jailbreakable (he doesn't jailbreak his phones). If I jailbreak it, can I activate it without going through iTunes or AT&T so I don't have to sign up for the data plan, or can you only do that if it is unlocked?
