App Store bug on certain iOS/Hardware and not others

I am about to submit an iPhone app to Apple for the first time. I was wondering: if they find a bug only in iOS 3.0 (for example) would they allow you to release only for iOS 4.0 (and above) even though you targeted 3.0 and above?

Likewise, if you have targeted the original iPhone device, but there is a bug found when your app is run on it, but not on any of the other devices, will they allow you to release for those?

Or is the answer to the above "NO. You have to debug, r开发者_如何学运维esubmit and wait yet another month".

Thanks!

No; if you set your deployment target to 3.0 and it doesn't work on 3.0 and above, then your app should and probably will be rejected. Your only option is to either thoroughly test on older OS versions, or raise your app's deployment target to a version which you're confident your app will work on.

You can change the deployment target to any version you want as minimal requirement... so if your app requires 4.0 or 4.2 you can set this and it won't have to run on old devices.

On the other side your app has to run without crashes on actual 4.3 devices.. you can't submit an application that only runs on old devices.

If you change the deployment target you have to recompile and resubmit.
