More evidence suggesting the imminent launch of a 3G iPhone, this time from the Wall Street Journal's Walt Mossberg.

Mossberg this weekend claimed a 3G iPhone would appear within 60-days. He was speaking at a conference in Washington DC. His comments emerged as he discussed mobile networks in the US, slamming services provided by networks there.

The technology columnist also spoke up for the Apple TV, but warned the limits of broadband deployment would affect the success of the service.

Mossberg offered no evidence for his claims but they are consistent with multiple claims from multiple sources, meaning most now expect a 3G iPhone to appear by June.
