Last time iPhone 4.0 was spotted in a server log, now it's been seen again in a developer's Pinch Media analytics. Sure, this stuff can and will be faked, but given that Apple typically introduces new OS versions in March, and that iPhone 3.2 is still nowhere to be seen, maybe they are concentrating on 4.0 and early tests are already underway?

'Tis the season to see rumors, if nothing else!
