    Don't hit the upgrade button. Some people w/ jailbroken phones have had some issues. Sync/backup your phone first. Next, restore as a new phone. Then use your backup to restore your apps, contacts, pics and settings.

    I agree with lungho. I had the same jailbreak... Did a straight upgrade and torpedoed my data connection.
