Filed under: CellphonesSo we've got it on authority that the second-gen iPhone is already well into testing, and numerous units are floating around in super secret pockets. A trusted source got a chance to check one out, here's what we've heard.
The first thing people will notice: the 2nd gen iPhone will be about the same size and shape as the first gen.
It will, of course, have 3G. And proper GPS!
The most noticeable physical difference is back of the phone is no longer metal -- the whole thing is glossy black, from top to bottom. The volume buttons are now chrome.
Because it's got a little less metal to deal with, it doesn't have quite as many angular edges. The battery is (still) not removable.
