iPhone crashes on upload from xcode

Hello. My problem today is that whenever I install an xcode app onto my jailbroken iPod, the whole iPod crashes when the app opens! After it takes the 2-4 minutes to restart, the app seems to work OK. I used AppSync and some coding that is offered from several websites to install without the $99 (blasphemy!), but the app exits xcode debugging with exit status 15.

On a side note, my music files and splash image don't seem to be working on the app, either. The game works fine, just no sound effects, and the fading splash screen is just white.

Thank You!

 

Probably. The one major problem is that I don't know how to remove these modifications. I actually did this once before (before a horrible incident involving my hard drive being wiped) and it worked just fine.
