Will not install on iOS 3.0?

I’m just putting the finishing touches on my app to release in the App store and was doing some compatibility testing. I found I cannot install my app on an iPod Touch (gen 2) running iOS 3.0. However, I can install on iPod Touch (gen 2) running 4.0 or 4.2. I’m using the latest stable build of Corona (591).

I’ve looked around in the forums and elsewhere and the only thing I could find that would prevent compatibility with 3.0 are custom fonts, which I’m not using. Are there other things that could be causing this issue?

I tested on this device (a borrowed one from a friend otherwise I might have caught this sooner) several months back (using 284) and it worked. Since then I’ve added a lot of features. The biggest being integrating the Director class and Beebe games classes. Do either of those have components that would cause this problem?

Thanks in advance for any insight you may have. [import]uid: 2595 topic_id: 13358 reply_id: 313358[/import]

I’ve tested on ipod touch 1st gen running 3.1.3 and it works fine with daily builds. I think Corona supports 3.1 and above. [import]uid: 13560 topic_id: 13358 reply_id: 49012[/import]

Thanks for the reply. In testing on the official iOS simulator, I can’t get it to work on anything pre 4.0 (including 3.2 on ipad).

I was just thinking that I do have openFeint in there which I know did remove support for 3.0 (because GameCenter support in OF and GameCenter isn’t available pre 4.0). Didn’t it come back with one of the more recent builds though (disabling GameCenter if you were pre 4.0)? [import]uid: 2595 topic_id: 13358 reply_id: 49068[/import]

Corona supports down to 3.1. But expect that to increase upwards as time goes on.

Apple’s Xcode/iOS simulators have not been historically good for testing backwards compatibility. Generally expect to test the latest iOS version when using them.

Good to know. I’ll see if I can have my friend to update to 3.1 then and test. Thank you. [import]uid: 2595 topic_id: 13358 reply_id: 49113[/import]
