Following the lead of C Spire, which began carrying the iPhone 4S last year, regional US carriers nTelos and Alaska Communications have announced that they will be carrying the iPhone 4 and 4S. The two carriers will both be launching the iPhone on April 20th at around the same price point. On nTelus, the iPhone 4 will cost $49.99, and the iPhone 4S will range from $149.99 to $349.99. Alaska Communications bumps each of those prices up by a penny, and both carriers require a two-year contract.

Both Alaska and nTelos use CDMA networks, and like C Spire, they're fairly tiny. nTelos has fewer than half a million subscribers across Virginia and the surrounding states, and Alaska is even smaller. However, unlike the larger T-Mobile, they run on bands that are compatible with current versions of the iPhone. While the iPhone is certainly spreading to smaller networks, not everyone is jumping at the chance to offer it. US Cellular, for example, apparently turned down Apple's terms, which it found "unacceptable."
