Sprint subscribers who have been waiting since 2007 for their carrier of choice to finally land the iPhone breathed a collective sigh of relief on Tuesday when Apple confirmed that the nation’s No. 3 carrier would soon offer both the iPhone 4 and the iPhone 4S. Sprint also confirmed on Thursday that it will indeed be offering unlimited data plans to iPhone users, and that pre-sales of the iPhone 4 would begin immediately while iPhone 4S pre-orders start on Friday. BGR sought clarification on the pre-order process following an anonymous tip we received, and Sprint has confirmed that iPhone pre-sales will be accommodated entirely online. Sprint’s retail stores will not have the ability to take iPhone pre-orders, and the carrier also confirmed to BGR that Sprint stores will not offer “Device Wait Lists,” meaning customers cannot add their names to a list in order to be guaranteed a device on launch day. Sprint will begin selling the iPhone 4 and iPhone 4S on Friday, October 14th.
