Keep your eyes peeled, cause iPhone 4 prototypes are turning up everywhere, or at least in two places. Photos of a second iPhone prototype showed up on a Vietnamese Web site, which right now won’t load. But ZDNet has lots of pics.
Remember, this is the one that’s a bit boxier in shape and will most probably launch with iBooks on it. Speculations are high that Apple will launch it in June; rumors have been circulating (this link points to Slashgear) that AT&T has been pushing up customers iPhone upgrade dates to June so that folks can get themselves one of these new-fangled iPhones.
