Universal app wont launch in iPad mode?

For some reason my universal app suddenly does not want to launch in fullscreen iPad mode, but it used to do so. I am really not sure what happened.

The iPad target is set to iPhone Devide 3.2 and the iPhone OS deployment target is iPhone OS 3.2 as well. I have set the Targetted device family to iPad.

Yet, the app keep launching into the iPad simulator in a small window indicating it is an iPhone app...

Is there anything else I am missing?

I开发者_高级运维 have tried all kinds of things, but running out of options. Any ideas are appreciated...

It's a native opengl app by the way, not using any .nib file for the display.

Turns out the solution was quite simple. Just restart xCode and delete the app's from the iPad. Seems this is the golden rule when things start to behave strangely...
