T‑Mobile has posted some technical specs about the iPhone 3G S. Apple has flatly refused to tell anyone just what chips lie inside the iPhone 3G S. The revealed specs are a 600MHz processor and 256MB RAM for the OS, double that of the 128MB in the original iPhone.
The RAM itself is going to make a huge difference. The new iPhone 3G S is said to load webpages almost 2 times faster that the earlier iPhone 3G.
