If you're a business traveller who relies on the iPhone's Google Maps app on the road, you might want to hold off upgrading your iPhone or iPad to Apple's new iOS 6 software, which was released overnight.
Since the Maps app is one of the big changes business travellers will notice in iOS 6 -- and since it's one of the most-used apps when we're on the road -- we've been keeping our ears to the ground, and we're hearing concerns about how iOS 6's new Apple Maps app works, especially in Australia and elsewhere outside the US.
Developers who currently have the testing beta version of iOS 6 installed are under a non-disclosure agreement, so the details of precisely what fails is pretty sketchy.
But much of the problem seems to be around street categorisation -- in other words, whether X Street is bigger than Y Street and thus better to drive down -- and the details of the turn-by-turn direction system.
Google is expected to release a dedicated Google Maps app in the relatively near future, but there's no release date as present, so there's no fallback option once you've upgraded or swapped out your iPhone 3G/4/4S for an iPhone 5.
Bottom line: if the Maps function is mission-critical to you this week and next, you might want to hold off on getting the latest and greatest iPhone and iOS version until everyone finds out what the real situation is with Apple Maps, or at least keep your older iPhone handy.
