Pioneer

Now there are 13 different carrier choices for the iPhone 4S across the United States. Not only this, but Puerto Rico has joined in the fun with its own local carrier Open Mobile offering the Apple device. The iPhone has come a long way since 2007, when Apple had a deal with exclusive carrier AT&T for the iPhone.

Oklahoma-based Pioneer Cellular is the latest regional carrier to announce support for the iPhone, and has started rolling out the device in its stores. Pioneer will continue to release the iPhone 4S at additional stores across the state every other week. Data plans with the carrier start at $30 per month.

Pioneer is set to bring a touch-screen car receiver to market that will integrate seamlessly with your iPhone or iPod touch. This either sounds like a great idea or the most distracting in-dash system ever manufactured. The AppRadio features a 6.1-inch 800 x 640 pixel resolution multi-touch display, Bluetooth connectivity for hands-free calling and an AM/FM radio. The real magic happens when you plug in your iPhone 4 or iPod touch 4th generation and start the vehicle.

Apps that have been modified to display on the AppRadio can be used directly on the Pioneer unit. Initial partnerships with app developers include Inrix Traffic, Motion-X GPS Drive, and Pandora and Rdio streaming music apps. More are sure to come on board, as the modifications required for an app to run on the AppRadio are relatively minor.
