    Hi there,
    next month I will go for an extended period (at least 6 months) to Taiwan (time to improve my mandarin ;)) and I'd like to keep using my iPhone 3G (purchased in the US). Will it work with a carrier other than AT&T?
    If not, is there a way to make it work?

    Thanks and happy holidays !!!

    What's your baseband (a.k.a., modem firmware)?
    You have to jb and unlock it to use another provider's SIM card.
    Go to iclarified for tutorials.
