    I have searched the previous threads on this issue and have not found a working solution to date.

    Here's the info:
    • Blackberry Pearl 9100, bought online, unlocked.
    • Blackberry Plan active and working on 8100.
    • On the 9100, Voice, SMS, Browser etc. works, however the device does not register on the AT&T data network.
    • I have wiped the device, updated the operating system, re-installed AT&T service books, and spoken with both AT&T as well as Blackberry Technical Support, without success.
    • Only the lowercase "edge" symbol shows with the AT&T SIM card. Interestingly, with an Orange Sim roaming on T-Mobile, the "3G" symbol shows. (I have considered switching to T-Mobile, but they do not have an unlimited international data plan).
    • Apparently, the software installed on the Blackberry does not support the AT&T data network, therefore the device does not register.

    Are there any known solutions / workarounds to this issue?

    Thank you very much for your assistance.

    then you are messed up because its an internal unit from RIM, return it.

    Thanks, I will try that.

    If I get another 9100, will it then work on AT&T?

    - o.k, I will look out for not getting a 0044.
    - I am located in the US; will try to get one from Canada.
    - exactly, what does "line up the bands" entail?

    Thank you

    it will be hard to get one from canada, nobody will ship to the us. I think rogers, telus, bell, etc might use 850/1900 which is what you want for att 3g. use unlockusa.com for $ 2 to unlock it.
