I have develop blackberry application using BB SDK 5.0 and tested it till 7.0 SDK and is run perfectly till 7.0.
I don't have the devices or simulator for 7.1 SDK, so is my application be able to run on 7.1 SDK also?
Thanks.
From my experience if you develop on SDK 5 it should run fine on anything above 5 (with the exception of 10 of course)
However, I would highly recommend you at least test on a simulator/device rather then just to assume all the functionality of your app will be there.
