    This one I have is (4.5) thats not from AT&T is causing some crashing and other stuff. I just want to go back to the old one until the official one comes out from AT&T.

    Besides that, I also may return this phone. I can not afford the monthly data plan as I work at a commission based job and with my commission check that fluctuates and is steadily falling, I need to have some flexibility.

    Go here BlackBerry - BlackBerry Desktop and Device Software Download Sites to get the OS for your phone. Go to the AT&T site. Make sure that you get the OS for the 8310. I believe that it is 4.2.2.170. Get it quickly because AT&T are just about to release a new version.

    • Uninstall the unwanted version of the OS from your PC.
    • Sync your phone to Outlook
    • Backup your phone
    • Install the original AT&T OS that you just downloaded
    • Run Desktop Manager
    • Connect your phone
    • Select Applications Loader in DM

    The downgrade should start after it asks if it should proceed.

    Don't return the phone. Just turn off the data plan until you can do better fund wise.

    I did that with my old TMo MDA.

    When you are bringing in more revenue, just call them back and add the data plan.

    I'm sorry to hear you have to even discontinue it
