BB Bold :: 9780 OS 6 Bundle 2647 Email Setup?

Its been a while since I purchased my Blackberry Bold 9780 (February to be precise). I was extremely happy with its functioning aand it never gave me any problems...until yesterday. I have a Apple Macbook on which I have loaded the Desktop Software to backup my data, transfer music, photos, etc.Yesterday as soon as I connected my device to my computer it notified me that there were updates for my device and if I would like to install them. I ticked on the necessary options to backup my data and initiated the update process. That was the last time I saw my device working fine. It took a while to update after which it finally showed up on my desktop software. The OS was now 6.0 build 2647. I safely disconnected my phone to check whether everything was ok. At first glance it was all good and that was until I went into the setup app on my device and clicked on email set-up. It just showed a small loader for a microsecond but didn't respond. To make matters worse, I couldn't exit the setup app and the device just hung up. After a hard reset, it did manage to enter the email setup app, showed me two options (Internet mail account, Enterprise account). clicking on any one of them bought me back to the same hang where the device just froze. Multiple hard resets later, took another route to find the problem. This time through my email message inbox---->options---->account management. This is where is showed me a message which read that it was unable to load my account settings and I ned to contact my wireless service provider. 2 hours on the phone with the tech supervisor from Orange and half hour of security wipe, left me back to square one. Issue not resolved yet, device takes ages to start and flashes a red light everytime before it boots....and most importantly can't setup any new mail nor can update the settings of the current ones.
