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.
