Gizmodo reviews the iPhone 3GS; they echo the incremental changes theme that Apple has going with both their hardware and software updates this week.

The iPhone 3GS is not an insignificant step forward in the iPhone family. The Nike+ support, magnetometer (compass), video recording, voice command, better camera, better battery life and faster data network are all improvements nobody would call a step backwards. But the biggest day-to-day improvement over the 3G is undoubtedly the increased processing speed, which is why Apple called this phone the 3GS (with the S standing for super fast) in order to designate that it’s basically the 3G, but better.

Can’t wait to buy it next week.
