i think you need to wait for the released version in a week for iOS as you are running a version from October that only deployed to Android. Tho it had Blackberry and iOS selections too.
well it looks like the 2 Premium version are available now as in Order but the 2 std versions are on Preorder.
are you saying you bought it in the last day and downloaded it ?
otherwise if you downloaded it a while ago iOS was not supported.
