here and get the latest Official OS upgrade. I have been using the .600 OS for a few months now but RIM has released .666 and .668 (668 being the latest). Read through All In One Guide - How To Upgrade Your Device - with Pictures & Videos a few times getting used to what is being said. But you do not have to wipe your device as stated in Post 3 = Wiping Device Memory Using BB Swiss Army Knife, the 6.0 OS does not need to be wiped. Once you have followed these instructions, you should have the latest and greatest OS for the Torch.
Remember that when you are going to install the new OS, make sure that your DM is closed, because it will interfere with the upgrade process.
Any other questions, don't hesitate to ask.
