    Get BlackBerry Desktop Manager from RIM's site. Get the the official OS5 release for your carrier (linked from RIM's site somewhere there I think, or search this forum). Install both. Connect your phone. Run DM. Backup. Choose the update option. Select OS5 and install (should show as a DOWNGRADE). It'll prompt for backup there as well. Do not disconnect your device until it says he upgrade is complete. If my post is not clear search the forums for how to install an OS on a BB phone. More detailed instructions are posted I am sure.

    Sorry. But I am assuming you are used to installing software packages and such.

    go to the search box in the top right hand corner
    search how to downgrade your OS

    if that doesnt help Google works well too.

    there are dozens of tutorials and topics on this subject, no need to start another thread on it.

    EDIT: I found this link http://www.lmgtfy.com/?q=downgrade+b...+os+crackberry
