    Can anyone confirm that a prepaid T-Mobile SIM (talk and text only - no data) will work in a factory unlocked iPhone 4S?

    I'm currently using a prepaid SIM in my software-unlocked 3GS and I'd like to upgrade it to a 4S. I have to turn 3G off to get a signal. My main concern is that the 4S lacks a toggle for 3G (there isn't one on the locked AT&T 4S anymore). Will it just default to T-Mobile's 2G network automatically?

    Thanks!

    Don't see why it wouldn't work seeing as it worked in your 3GS

    It will work with any GSM sims. Should be no problem what so ever. I am picking one up for my daughter within the next 2 weeks :)
