Whoa, stop the presses -- we're not sure if this is officially in the pipeline or if it's just a matter of wishful thinking, but Sprint may not be the smallest carrier in the US to offer an iPhone 4S for much longer. That's right: regional carrier C-Spire (formerly known as Cellular South) has the iconic device splattered front and center on its home page, stating that it's coming soon. We're not certain if the iPhone 4 will be offered as well, and no specific availability or pricing is given yet, but you can sign up to be notified as soon as more 411 is ready. The possibility of one of the little guys getting the iPhone is an exciting prospect, since it may lead the charge for more regional service providers to get Apple'd up. We love rooting for the underdog, after all.
