edit: Looks like someone posted about the accelerometer issue already.
Flashed this over and came across a couple issues.
Checked under settings and orientation is checked, but no apps will orient themselves in landscape mode. In other words everything is also in portrait and doesn't rotate when I rotate the phone.
Also tried out Google Sky Maps and it doesn't orient itself correctly. Though this could be because of the issue stated above, but wasn't sure if Sky Maps uses some other sensors or something to change as you move the phone around. Have all the Location settings enabled so I know thats not adversely affecting it.
Just helping weed out the bugs.
