I flashed using the 1.2 firmware this morning and thankfully have had no problems with it. Glad to have it as I've not experienced any of the bugs from 1.1.1 and CPU usage seems to be 'normal' i.e. no 100% CPU utilisation until rebooted.

Next time there's a leak before an official release I think I'll wait...lucky this time but don't want to push my luck again.

If only there were more regular releases from Nokia to fix the bugs which REALLY make the phone a pain to use at times.
