The awesome Andy I has got a nice weigh in and round up all about The (Increasingly Plausible) Miraculous Engadget (and Gizmodo) iPhone 4G.
Okey-doke. Given that they didn't say "It has the same guts as an iPhone 3GS," we have to conclude that this is indeed a rogue Apple iPhone prototype.
Interesting. On a number of levels.
I was on the "it's a lame knockoff" bandwagon when this first came out, but the evidence seems to be mounting for this being a real thing (either that or greatly crafted PR from Apple).
