I bought my S4 through AT&T. When it was paid off I switched to T-Mobile. The phone still boots up with the ATT screen. There are ATT apps still on it that work. I am assuming that any download/upgrades would be for the AT&T S4 and not for T-Mobile? 5.0.1 is available for AT&T but not for T-Mobile. I have 4.4.4 and want everything to be current. The phone says I am current at 4.4.4 thus my question.
Thanks,
Randy
