I have recently inherited an iPhone 4 tied to AT&T. I would like to unlock and use it on T-Mobile. After perusing SoSH and running a few searches, I haven't been able to find good info on the process. For various reasons, I don't think doing it the "legit" way through AT&T will work (no the phone isn't stolen...if you really want to know why, I'll PM an explanation)
Also, should I be Jailbreaking the device while I am under the hood?
A Google search turns up a lot of "go to my website and download my tool" stuff, mostly videos - which I don't find entirely trustworthy.
