How to set up your new unlocked BlackBerry (ASK JOE)

“I got a Curve 8900 from T-Mobile and have it unlocked for use on AT&T. Now what… Is there a good answer. I am reading everything from just put in SIM, download generic service books, wipe device, download OS delete vendor file. Please help.”

You have got it down, that’s exactly what you do. But you may also want to configure your APN to work with AT&T’s network.

Options> Advanced Options> TCP/IP. APN should say APN: wap.cingular Username:WAP@CINGULARGPS.COM Password: CINGULAR1

Something else that may make life easier is AT&T had begun sending out its own carrier specific service books for the 8900, so you may be able to bypass all the headache of manually setting up your T-Mobile Branded 8900 for use on AT&T’s network!

Thanks for the question Mike.

    Hey Joe,

    Thanks for all the great tips.. Another question for ya.

    How would I go about backing up all my 3rd party applications AND the data in them? For instance, I know I could just REINSTALL datepedia for instance, but that does not add in the 30 or so birthdays that I have stored in there.. Just curious with all the new berrys coming out. Thanks a lot.
