    Hey Guys,

    I recently unlocked my iphone which is at 3.1.2 firmware, I am thinking about 3G Service while T-Mobile has allowed me to try it free for a month..

    The thing is I can't use the 3G Service, it will say "no service", and just connect use EDGE.

    I am wondering if anybody knows if it's possible to use the 3G Service with T-Mobile on an unlocked iphone.

    no you can't, att and tmobile frequencies are different so since the iphone was made for att it will only work for that.

    You can only use Edge on Tmobile.
