As a Sprint investor, I'm definitely alarmed; but I do believe they've positioned themselves well going into the iPhone launch. They've done away with a lot of the extra features (premiere rewards program, return policy, 1-year contracts, unlimited tethering to name a few) and raised a few fees (upgrade/activation and insurance) in order to be able to keep their unlimited plan at the same pricepoint even with the influx of iPhone users, and even with the diminished profit margin that selling Apple products yield. The whole time Apple was showing off "Siri" today, it just made me think how that's yet another very data-heavy use of your phone and I think Sprint being the only carrier with truly unlimited data could be a reason for some people to switch. I realize the vast majority of people don't even use 1 GB of data a month; but for once in the last 5 years or so, they actually have a competitive advantage over the other carriers that's not just price. Now Sprint just needs to do away with WiMax and build out their LTE network as soon as possible. Their October 7th "4G Strategy/Network Update" should be revealing and I'm hoping for good news from that front.
