I called the Metro guy that flashed my phone and told him about flashing my phone to another custom ROM, and he told me it will mess up the MetroPCS service, and i will be charge with another $50 to reflash it back to Metro. Can some one help with this? I really want to use MightyROM ( good battery life, nice interface) but i dont want to spend any unnecessary money on Metro, thanks
