I just got a replacement iphone today (still not activated). So, what do I need to do to get it activate? Jailbreak with pwnage tool maybe? Since I'm using t-mobile service. Thanks in advance.
You can use a pay as you go sim from AT&T.
If you want to hacktivate, pwnage is amongst the programs that will hacktivate. Make sure to check the activate option (or it might already be checked, but I don't remember).
Yes, the cat above is right.
Pwnage will hactivate by default but I would suggest using an AT&T sim to activate it if u can. Even old inactive sims will get the job done or anyone's AT&T sim, prepaid etc.
