iPhone应用程序可以在iPad上正常运行，但不能在iPhone上运行

Question

I've got a problem with my universal app that I just recently ported to the iPad.

While it works fine on the iPad, on the iPhone 3G it shows Default.png and then goes to a black screen.

It even showed the home screen after Default.png once, with all the icons messed up - and the home screen was still scrollable.

I've tried everything to get it working - cleaning the app and deleting then reinstalling the app but they don't seem to work.

I've rebooted my Mac and my iPhone but doing so doesn't seem to work.

Also - the app works fine in the iPhone simulator, so I'm wondering if it's my device.

Update:

I converted the app to a universal application using Xcode's 'Upgrade current target for iPad' function so there are different XIB's for each device.

I also don't have any other device to test it on - just an iPhone 3G and an iPad.

Problem solved. Rather easily actually - in Xcode's upgrade process, it changed an entry in the plist to not find MainWindow. It changed the entry 'Main nib file base name' to 'Main nib file base name (iPhone)'. I don't think the iPhone knew where to look for the nib because its plist entry was changed.
