Three20 project crash on jailbroken iPhone3G, works fine on 3GS without JB

i've got a strange problem: i've made a simple app using three20 framework, it builds without error, after installing the app on 3GS it works great, but after opening it on jailbroken 3G ot crashes with following errors:

You are crazy to try and support Jailbroken phones. My advice - stop now before you drive yourself crazy. Apple frowns upon jailbreaking for many reasons, this being high on the list. There are way too many possibilities of jailbroken configurations and setups that in order for apps to support them, they have to do tons of (normally) unnecessary checks and error prevention.

I think the problem is more likely to do with the fact that the iPhone 3G and 3GS use arm6 and arm7 respectively. The binary you're building is not compatible with the older 3G.

In the build for three20 (and your project) try setting Build Active Architectures Only to on.
