Wall Street Journal technology columnist Walt Mossberg is moving to distance himself from previous claims to his comments on a future 3G iPhone.

Mossberg is now saying that his previously-reported claim that a 3G iPhone would ship "within 60 days" was based on the same speculation other Apple watchers have access to, saying he has no inside track on the company's plans.

As reported in Silicon Valley Insider, Mossberg states: "If I knew when this date was, why would I announce it in the middle of a sentence at the Finnish embassy, rather than report it in the Wall Street Journal."

The evidence continues to mount to suggest a 3G iPhone release date is already written into Apple CEO Steve Jobs' diary in invisible ink. Aside from continued chatter from across the analyst web, Apple's latest release of the iPhone SDK includes code designed to support a 3G chipset from Infineon.
