I have a couple of att iphone 4s16 that i am putting tmobile sim cards in to see if in the about section carrier will switch over. i was wondering if it does switch from att to tmobile does that mean the phones are unlocked.
i also ran into a problem where if i left the tmobile sim cards in the att for a little bit of time it would switch in the carrier section but then reboot itself and said that it needed to be activated, when i went to activate the phones i no longer read the tmobile sim card and would only activate using the att sims. Has anyone else ran into these problems?
