Xperia X10 :: Security Pattern Lockout And Gmail Info?

I set the trace a pattern security system for the phone. Later when trying to do two things at once I got the pattern wrong five times. I then compounded the problem by getting the succeeding attempts wrong as well until the phone locked me out. Like many others it seems I set-up my gmail account without recording the pertinant details, gmail address and password, these are the requirements to unlock the phone. The official X10 user guide is no help on the subject. I have also been to various websites looking for advice and have found no information at all, apart from don't do it of course! I went to a phone shop and their advice was to use PC Companion to reset the phone but of course I need to mount the phone in order that the software sees it. I am resigned to resetting the phone as the solution as I am backed up but even if I reset I will still need the gmail info to enable all of the Google features. I know it is the result of being a dufus but it seems like a bit of a terminal cul-de-sac at the moment.
