iOS Own developed iPhone app crashes with 3.0!

[tomast80]

My friend and I have developed an iPhone app together. It works fine with iPhone 4.0, but the app crashes almost directly with 3.0. I have made sure that I don't use any functionality that has been released after version 3.0.

Can someone please give me some advice on what i should do in order to make it work also on 3.0? I would be very grateful!

Are you able to run gdb on the iPhone that's running 3.0? Try setting a few breakpoints to find out where it's crashing and take a look at the backtrace.
