I think you've missed something in process when you're trying to make your phone able to add those cracked app (cuz i did, hehe).
It happened to me, too. Maybe all those error messages above, I guess I got them all, lol. So, now after my three days of continuous restoring my Touch, here's the best way to add your cracked app to your phone or Touch.....
First, restore you phone again! (Yes, you need to.)
Second, follow this "How to" ;

** Btw, this "How to" missed something**
After step 9, you need to move "mobileinstallation.bak" (that had been created) onto your desktop or somewhere else. Then delete "mobileinstallation.bak" in your winscp.
Then follow step 10 and 11.
After that, * you need to delete all applications that you have in your iphone *, sync it again. Then you can continue step 12 and enjoy!
Cheers!
