If you're an iPhone or iPad owner, you might have been disappointed that the Delorme inReach two-way GPS communicator launched with app support only for Android users. That's fine if you're trekking with a Casio G'zOne Commando, but not so hot if you're of the Apple mindset and get stranded canoeing down the Amazon. Thankfully, Delorme just posted an iOS version of its Earthmate app that will let your Cupertino-designed gear send either text messages or SOS beacons through a paired-up inReach unit. As before, the handheld relies on its own GPS positioning and embedded locations in messages to keep friends and rescue crews updated anywhere the device can get an Iridium satellite lock-in. It'll still cost you $250 for the device and $10 per month to stay linked up; even so, there's a real chance you'll be texting your friends from your iPhone in Mali, assuming you haven't had to call a rescue helicopter first.
