I have Tier 2 pure landscape working in iOS 5.1 and 6.1 fine in v1076 and v10811.
What version of AppGameKit are you using and where did you get the template?
Did try using the command agk:
rientationChanged(3) (or 4)? It is not documented in the help code, but I have talked about it in various places for orientation control.
There are two sets of things in the Info.plist file, one sets what is allowed and the other sets the initial orientation:
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeLeft</string>
<key>UISupportedInterfaceOrientations</key>
<array>
<string>UIInterfaceOrientationLandscapeLeft</string>
</array>
The example above sets for one orientation only, AppGameKit landscape 4. AppGameKit landscape 3 would be LandscapeRight.
Will you show us your display setup code?
