ipad app minimum OS requirement mistake

I've recently submitted and had approved an iPad only app to开发者_StackOverflow the app store. My problem is that I acccidently left the Minimum OS requirements to 4.2. Doh!

Is there an easy way to change the OS requirement to 3.2 so that the original iPad can download and run it? e.g. through itunes connect. Or am I going to have to change the binary and resubmit as an update?

Be kind - this was my first attempt at submitting my first app to the app store.

Thanks

I think you will have to submit a new binary, as the minimum OS requirement is encoded in the info.plist of the application bundle.

Make sure you actually test on an 3.2 device first, though, as you may have inadvertently used a 4.2+ API.

You need to release an update to change that requirement. Note that when you change requirements you can never require a newer version, in other words, while it's OK to change it from 4.2 to 3.2, if later you decide to use a new feature from 4.2 you can't change the requirement back to 4.2.
