OnStar's solution, an upcoming Bluetooth app that will read text messages and status updates to you and, somewhat more interestingly, lets you speak a custom message that will be transcribed to your recipient. Fascinating? Absolutely, but we can't wait to hear what sort of fun and cheeky mistranslations come out of that feature. You can also post voice messages to Facebook and say things like "call back" to return a call. The app is, as of now, intended for Android devices only and is set to hit the Market sometime in the first half of the year, and at least initially it'll only work on cars that have Bluetooth or those equipped with the company's new aftermarket mirror, though you'll have to be paid up on your OnStar dues if you want to use it. Full details in the PR after the break.
