We are submitting an app to the app store and trying to figure out if we should submit for iOS 5.0 or iOS 6.x.
Last time when we tried to upgrade an app from iOS 4.3 to 5.0, it wouldn't let us, since some users wouldn't be able to get the upgrade. (I can't remember the exact message, but it could have been this, a difference in hardware).
I was just wondering if we submit for iOS 5.0 now, will be have to submit a new app with new bundle name if we want to use features in iOS 6.x later.
