ATT or Verizon or T-Mobile

Thanks guys major info here, T-Mobile sounds like a plan.

Pod - I just bought that chip to unlock my 4s, hopefully it'll work and like last time I will be bring my BB for basic needs until the 4s gets sorted

If you buy your T-Mobile SIM here and they don't have a micro-SIM in stock, get a regular one and I can do the conversion for you, I have the tool.
