When I tried booting it up and it wasn't working, it'd sit for several hours and not move from the 'Nokia' screen. It would come up with the 'Nokia' screen, then after a period of time (minutes) it would flash black, then back to the 'Nokia' screen, and so on.

I just uninstalled VideoCenter and the boot up was quick. But, only time will tell.

Do you have kagu and/or a2dp installed?
