It looks like Sprint will indeed be getting the iPhone 5 soon--perhaps on Tuesday.
Apparently confirming earlier rumors, a screenshot published by Engadget purportedly of a Radio Shack inventory page lists a 16GB and 32GB iPhone 5. It was suggested in early September that a Sprint iPhone 5 was in the offing when an internal carrier memo informed employees of a vacation blackout from September 30 through October 15 due to the "possibility of a major phone launch."
Apple might give us more information on a Sprint iPhone on Tuesday, when the company is widely expected to take the wraps off a next-generation iPhone during a Cupertino, Calif., press event. Apple sent invitations to the media last week that featured a cluster of four iOS icons and the tag line "Let's talk iPhone."
Come back at 10 a.m. Tuesday for News.com's live blog of the event.
