The evidence seems to be mounting that the new iPhone will be significantly thinner than the 4S that came before it.
Evidence comes via leaked pre-production parts of the iPhone 5, such as enclosures. The enclosure is 58.47mm wide, 123.83mm long and 7.6mm thick. The iPhone 4S is 9.3mm thick.
To move from a 3.5-inch to a 4-inch screen, the form factor had to be elongated by 8.63mm. Additionally, the headphone jack has been moved, and Apple has moved to an 8-pin dock connector, compared to the current 30-pin seen on all iOS devices.
