Sprint is on a bit of a roll recently. Sure, there were some problems with its Google Voice integration and the company is still losing money, but it's adding subscribers at an impressive rate and now it's tied Verizon for the number one spot in a recent customer satisfaction survey. The American Customer Satisfaction Index showed Sprint had made significant gains in the last three years, rising from dead last amongst the big four with a score of 56 in 2008 to match Big Red's field-leading 72. At the same time, both T-Mobile and AT&T saw small drops in their satisfaction scores, with AT&T hitting 66 points -- its lowest rating since the launch of the iPhone. Of course, with T-Mo hemorrhaging customers and the reanimated husk of Ma Bell claiming the ignominious title of most dropped calls, we can't say we're particularly shocked.
