Like we said, Passbook in iOS 6 is going to steal a few tricks from flight apps like Mobiata’s $5 FlightTrack (and $10 FlightTrack Pro), making the apps seem somewhat less valuable.

Whether or not Passbook replaces these types of apps remains to be seen; in any case, Mobiata isn’t going down without a fight, and has just released an all-new, free version of their FlightTrack app for both iOS — and Android.
