    So I just bought an iphone 4 off the street. The iOS is 4.2.1. I have T-mobile sim. I read on the Gevey Sim website (from Applenberry.com) that it only works with Apple original firmware. So my understanding is if I were to jailbreak with RedSn0w, then I would have a modified firmware. So then how can I jailbreak and still use the Gevey Sim? Please help, thanks in advance.

    PS: which one is better, RedSn0w or greeenpoison when using with gevey sim?

    I think you are OK jailbroken with grevy. I certainly haven't read about an incompatibility. I prefer redsn0w.
