Installed (upgraded from .130 normally with BB Desktop Manager) without any problems. No errors during migrating applications, settings, etc.
A few minutes of testing show that...
NO tabbed browser. Jerks.
Wordpress (0.9.0.157, restored settings, upgraded to .169, that works great, too)
App World (was stuck at "Loading" until I alt-tabbed to find a hidden error message on Home screen saying it can't connect to servers. It loaded the second time just fine.)
Music still has that annoying bug/feature where for Volume Up you need to kinda hold the + volume button for a while.
Unsynced Music didn't want to play anything, not that I'd ever use it
Facebook asked me for a re-download (of 22.214.171.124), but works fine
Flickr and ICQ ask for re-download, too, which I won't do right now. I need to download Viigo and gTalk and will post again.
