Searching Mobile Networks Problem... Need Help.

[Elma_VOLI]

So I bought a unlocked blackberry bold 9000, it use to be on AT&T, I'm using T-Mobile and I can't figure out how to connect to T-Mobile.... Need Help.

You need to take your T-Mobiles SIM card and insert it into the SIM slot of your unlocked Bold 9000 Blackberry, update the service books and get EDGE.

You will also need to set the unit to 2G in mobile network options under manage connections
