My blackberry came up with a software update yesterday so I downloaded it, which all went fine. However, when I go to install it, it comes up with verifying update and then reboots itself and nothing has happened, tried this 5 or 6 times. The first couple of times said I needed to clear out some personal data which I did, and this message has now stopped, but it still doesn't seem to be installing the update.

Any advice would be much appreciated
