As a general rule, customers tend to be quite satisfied with their Apple purchases. App Store faults aside, the company makes great products that are loved by millions of people around the world. The iPhone 3GS is no exception; AppleInsider reported today on a ChangeWave survey about customer satisfaction with the 3GS.

The results were largely positive. The 200 person study found that 99% of respondents reported being satisfied with their purchase. 82% of those people stated that they were “very satisfied” with the 3GS. This is a substantial improvement over the satisfaction scores of both prior generations of iPhone, and is a testament to Apple's ability to adapt to meet customer needs.

When asked what they disliked about the iPhone, 55% of respondents chose the AT&T network. 41% complained about the battery life. This shouldn't really stand as a surprise to anyone; ATT has a lot of issues as a carrier, and they are famous among iPhone users for dropped calls and slow connectivity. That's part of the reason why Apple is going to get the hell out of their exclusivity arrangement the instant it becomes possible.

The most-loved iPhone feature was the touchscreen, with 45% of the vote. Ease of use and the speed of web browsing were two other popular features. Most customers who switched from a different manufacturer to the iPhone came from Nokia (11%), RIM (9%), Sanyo (8%) and Palm (6%). This apparently means that some users tried the Pre, dropped it after a month or two, and ran to the iPhone 3GS instead.
