Ok, So I just wanted to be clear. I have a friend that has a VZW Droid 4 and wants to switch to T-Mobile. He has already done an OTA update for ICS. Is it possible to switch to T-Mobile? I thought maybe it wasn't at first because the OP said that you needed to be on Gingerbread and then update to the ICS rom, but it looked like after reading more posts, you just needed to be on ICS. So this phone actually have GSM capabilities? Cool.
