According to Apple, apps on the iPhone 3G S will load twice as quickly as they do on previous versions of the phone. Apple also claims to have made headway with the new iPhone's 3D graphics, while at the same time improving the battery life. But nothing puts these claims into perspective better than hard numbers.
An over-zealous webmaster at T-Mobile Netherlands seems to have erroneously published specifications that Apple has closely guarded since the announcement of the 3G S. The information has since been pulled from the page, but, as we all know, nothing disappears off the Web without a trace.
As we can see from the screenshot, the 3G S packs a 600MHz processor (similar to that of the Palm Pre) and 256MB RAM. The earlier iPhone had a 412MHz processor and 128MB RAM. Twice the memory should certainly speed things up.
