    A friend of mine has offered to sell me her (unlocked) AT&T S3. I'd plan on using it on T-Mobile. Two questions:

    1. Will I have to root and run a ROM, or will the stock AT&T software/touchwiz work as-is?

    2. Can the AT&T phone work on T-Mobile's HSPA+ 42 MB network, or will I be relegated to 3G due to frequency band differences?

    Appreciate any advice.

    1) You will need to unlock the phone. Many web sites offer this service for a small fee. ($20 is a good est.)

    2) No HSPA+ for you. You will only get 2G edge that I am aware of.

    I'd sell your S3 to someone on Ebay or something then buy the Tmo version. That's what I would do! Or look into another prepay service like Strait Talk where you can buy an ATT SIM card and continue to use their HSPA+ if service in your area is good.

    Hope this helps!

    You don't want T Mobile! Their coverage is horrible...worst among all minor carriers
