As Apple unleashes the iPhone 4S on AT&T, Verizon and now Sprint, the biggest question on everyone's mind is how much will the phone really cost? As the third US carrier to sell the iPhone, Sprint has confirmed it will offer the device with the same unlimited plans as the other handsets in its lineup -- much to the relief of loyal customers hoping to make a belated switch to iOS. But we're betting those of you willing to swap providers are just a little curious as to how the plans stack up. Fortunately, we've crunched the numbers for you, so all you need to do is meet us after the break for that bottom line.

The bottom line:

The cheapest taste of the iPhone comes courtesy of AT&T with 450 minutes and 200MB of data for $55 before additional taxes and fees -- but sadly, those numbers won't afford music / video fanatics very much streaming. Per month, the plans range from around $55 for the lowest end of the range to $170 for Verizon's unlimited talk / text and 12GB worth of data. Sprint's plan sets itself apart from the pack by offering truly unlimited, uncapped data as part of its voice plans whereas the others taper off at 12GB or even 4GB.
