Apps Crash on iPhone 4 but not on iPod 3G

[the G]

Hi there,

I have an iPhone 4 and iPod 3G. They are both on iOS 5.0.1 and both are jailbroken. I have an app called JeFit, when I want to view how to do a certain workout on the app (which is free and is a work out app) the iPhone crashes but the iPod doesn't. Any suggestion to why and how it can be solved?

Please and Thank You!

Just a guess, try with cellular data turned off, basically turning the iphone into an ipod

Tried that but it didn't work. Any other suggestions?

Reinstall the app, restart the iPhone, and if that doesn't work rejailbreak? It's probably some file or something making the app crash.

Nevermind guy. I got it. It turned out spire was causing the problem. I removed spire and the apps works fine now.
