I keep reading about people wanting to jailbreak their iPhone and take it to Tmobile. What is the point??? I could see taking it to Verizon but Tmobile? I am not going to pretend that AT & T service is great but I do not see Tmobile as being a big upgrade at all. Hardly seems worth the effort of jailbreaking and from what I understand you do not get updates if the phone is jail broken. I am sure I am missing something. I do not claim to know a lot about jailbreaking a phone. I will say I have tested about every cellular carrier out there and Tmobile is not that good.
