iPhone waltzes into top spot of US phone satisfaction index

We know almost too well how smartphones perform in US market share; what we don't usually see is how happy customers are once the shrink wrap's off. Going by a newly-expanded American Customer Satisfaction Index, it's the iPhone that most scratches the itch at a score of 83. Despite having just been added, Apple was noticeably ahead of a three-way tie between HTC, LG and Nokia at 75. You might not want to look if you're a freshly-minted RIM executive: the BlackBerry made its freshman debut on the charts at the bottom, or 69. Big carriers have their own reasons to wince, too, knowing that smaller carriers like US Cellular and TracFone scored higher on the happiness meter than incumbents hiking service fees. While there's definitely some wiggle room for your own experience to have been better or worse, if you were an iPhone owner on a regional carrier in the past few months, you were statistically the most likely to be on Cloud Nine.
