This looks good. Have you done this before and did you run into any problems. Also, about how long did this take to complete.

I have loaded OS's on blackberrys many of times. It's the same no matter what blackberry model you have. just make sure you have the correct OS for your device from you cell provider. it takes aprox 1/2 hour to complete but if you have never done it before give it a little more time. Also to be on the safe side to a backup with the Blackberry Desktop Manager before doing the update. Any question just ask.
