There have been rumors going around for a while that Sprint would be added as a new carrier for the iPhone 4S, and today Apple made this official. Our very own Jeff broke the news before everyone else earlier today, but it’s now a done deal.

You’ll be able to pre-order or buy the iPhone 4S for Sprint, as of October 7th…

But that’s not it, as iDB reader Azharhamzahya noted in the comments section below, Sprint will also get the iPhone 4, too.

Let’s wish Sprint good luck as they will have to unload $20 billion worth of iPhones during the next 4 years.
