Crash on iOS 3?

Many players reported to me that the app crashed on their devices.
Most of them used iPod Touch 2 gen/ iPhone 2g,3g and iOS 3.

Does anyone know what causes the problem?

Thank you.

Which version of Corona did you use? The latest daily build is iOS 4 only:

Also, did you use custom fonts? That feature isn’t supported on iOS 3. [import]uid: 12108 topic_id: 8388 reply_id: 30006[/import]

I used Corona.268 to build my app before.
So the app can be installed on both iOS3 and iOS 4 (but crash on iOS3)

I did use custom fonts~ I think that is the reason!
