Though we thought that TomTom would bring us the first turn-by-turn GPS app for the iPhone, AT&T is offering an alternative of its own. On Tuesday, the carrier released a version of its AT&T Navigator specifically for the the iPhone 3GS and earlier iPhone models with the OS 3.0 software update.
Features include voice-guided and onscreen directions, automatic rerouting, real-time traffic updates, a points-of-interest database and regular map updates. You'll also be able to search local gas prices when you need to fill up your tank.
Though the app downland is free, a $9.99-per-month subscription fee will automatically be added to your AT&T account. The app is now available for download from the iTunes app store.
