    I got a new iPhone literally 2 hours ago, and I want to use it with T-Mobile. I know I need to jailbreak it and unlock it, but how do I check what iOS version I have to know what jailbreak method to use without activating it?

    I'm assuming it has 4.2.1 since that was released 11/22/10, but I don't know for sure (hopefully it has 4.1). Any help is appreciated.

    Edit: just remembered that TinyUmbrella shows firmware version - looks like I'm on 4.2.1 Now to wait for sinfuliphone to come back up so I can try and find an untethered jailbreak.
