A MacTalk.com.au forum thread has revealed an icon in the iPhone OS 3.0 SDK of the, previously referenced, unreleased iPhone 2,1 model. The icon appears to be exactly the same as the iPhone 1,2 model which is, of course, the iPhone 3G.

Of course, with the icon being so small it’s hard to say whether or not there are any physical changes, however, the iPhone1,1 (1st Generation iPhone 2G) icon does appear distinct and physically accurate in the images. Keep in mind that iPhone 3G (iPhone1,2) icons were also spotted before it’s release with only slight differences.

This is not a groundbreaking finding, but it is consistent with circulating rumors that next generation iPhone will keep a similar form factor to the current model.
