We’ve been trying not to stir the iPhone rumor pot too much lately, but it seems like details are starting to come out that we believe may just be legitimate. Ryan over at Engadget heard a few things from a trusted source that match up with a couple of things we’ve heard, plus he got a few things we weren’t sure about.

For starters, we had heard that the 3G iPhone would likely be just a tad thicker than the current model, which seems to match up with what we read. Physically, Apple may be doing away with the two-toned back color of the iPhone, opting instead for a smooth black finish. The headphone jack will no longer be recessed into that hole of frustration, and lastly, the thing will have full-on GPS.

Engadget is saying that the next iPhone could ship as early as July. We are thinking it could be as early as June. We know for a fact that there is at least one person here in Seattle who has one, and that the person doesn’t work for Apple. Apple typically doesn’t seed these things outside of their organization until they are in the last phase of testing. That leads us to believe that these are just about ready to launch. What do you think? This is all a bit too exciting for us, as we die a little inside with each day that passes where we have to use EDGE on our iPhone.
