XCode 4.2 + Iphone 3g can't run app

Question

When I created a plain vanilla Phonegap application and try to run it on an iPhone 3g with IOS 4.2 it doesn't run. The IOS deployment target is set to 4.0 and everything does build successfully

This all happened after I installed XCode 4.2 with IOS SDK5. Running apps on the simulator is no problem.

Anyone who knows how I can get it running again?
