Debugging on iOS without a paid developer membership (3.x)

I currently have it set up for Xcode to Build & Go onto my iPod using this: http://il.youtube.com/watch?v=CHOVdi-kPV0 (A script to tell Xcode that it doesn't need to codesign).

I am trying to do that now, and only calling the iOS4 code if the device supports it, but I can't get it installed. GDB ...
