picked up my PE on Woot for $80.
Wanted an HP touchpad, but missed out on that so jumped on the PE when I saw the email.
Came here, read up on 2.2 procedure, immediately charged and updated to 2.2.
Also read here on the reg bypass issue.
Also read here for which APKs to get, and where to find them.
Also read here for NO lock APK.
I haven't rooted yet to use LCD2eink, but considering it.
So, big thanks to the group here for turning my $80 1.6 Android into a 2.2 android that I can surf, Facebook, control XBMC without an unlock screen, use Circle launcher, and hunt the Amazon market at my leisure.
Very glad I found you!
