The S really does stand for speed in the iPhone 3G S, as the folks from Anandtech have tested that the iPhone 3G S is currently the fastest web browsing phone of the current generation of "blockbuster" smartphones, including the T-Mobile G1, iPhone 3G and, perhaps most notably, the Palm Pre. We talk to Anand from Anandtech about the test results, and get his extremely informed opinion as to why the latest iPhone can beat all comers. His take? On top of the fact that the iPhone 3G S actually has a faster processor than the G1 or 3G, the iPhone OS has been developed for a few more years than any of the other OSes, which leads to significant speed improvements and optimization. Anand thinks that materially, the Palm Pre and 3G S are extremely similar devices, and that the Palm Pre still has lots of room for speed improvements in the browsing experience, especially if Palm doubles down on optimizing code. Keep in mind, these aren't necessarily the 100% conclusive results, and much of the experiment depends on network bandwidth and coverage. Take, for instance, CNET TV's unscientific test in San Francisco, where the Palm Pre tended to top both older iPhones. Distributed by Tubemogul.
