iPhone? It seems as though you're finally about to be in business. After a chat with a freshly-briefed, forthcoming sales associate, TUAW is reporting that the carrier will start offering an Apple device of some sort next month alongside existing data plans -- providing some confirmation for the recent Wall Street Journal report. Things get a bit cloudy after that in regards to exactly which handset the carrier will obtain, but the sales force is currently getting familiar with the iPhone 4. Regardless of which iPhone Sprint ends up procuring, it's getting fairly impossible to shake the (seemingly) obvious. We'll see in a month, eh?
