Engadget reports that Apple's forthcoming 3G capable iPhone will incorporate a GPS module but be only slightly thicker than the current generation model.
Engadet's visual description of the device largely mirrors that given by iPod Observer earlier this month that depict a more rounded phone with a glossy black back, but adds that the much-despised recessed headphone jack will be replaced by a jack flush with the device body.
The 3G iPhone is largely expected to be introduced at this year's WWDC conference, with probable shipping in July. Engadget is not typically a source of original Apple rumors, but claims this information comes from a "trusted source" who has had first hand experience with one.
Analysts have suggested that June 9th will be the launch date for the 3G iPhone at Apple's Worldwide Developers' Conference.
