Turn-by-turn directions
iPhone OS 3.0 brings support for turn-by-turn directions, making the iPhone a fully functional GPS device. The bad news is that, along with MMS, we'll have to wait until later this summer to get it. Directional services won't come from Apple, but will instead come from third-party apps. TomTom will be the first company to offer an app; a TomTom executive demonstrated it at WWDC 2009.
From what we could tell from the brief demo, TomTom's service looks promising. The interface was attractive and the audible directions were clear. TomTom will also offer a car kit that will secure your iPhone to your windshield or dashboard while charging it at the same time. That's good news for a device that sucks up juice quickly.
We're concerned with how much the app will cost. TomTom will offer a "range" of U.S. and international maps, but that's as much as we know. GPS maps are not cheap, so we'll be interested to see how TomTom will package and price the content to make it affordable for consumers and profitable for TomTom.
What's more, we're curious how much memory the maps will consume and how the app will integrate with the iPhone's other features. From what we understand, we'll be able to make hands-free calls and play music on our car's radio while getting directions. Unlike the Palm Pre, however, the iPhone doesn't multitask (we have more to say on that below). If the GPS feature has to suspend because you get a call--just as the iPod player suspends when you take a call--then things could get tricky. We suspect, though, that Apple and TomTom have this covered.
