iPhone prototype N94 leaked, possibly to be an iPhone 4S

There are lots of crazy rumors flying around about the new iPhone announcement coming later on this year (or as soon as next month), but this is one of the more credible. The picture above comes from a site called UbreakIfix through our friends at Engadget, and purports to show a prototype for the iPhone called the N94. It's a long story (which you can click through to read yourself), but essentially, the latest rumor says that this device is the latest testing version of what may become an "iPhone 4S," a slightly cheaper version of the iPhone 4 set to be introduced right alongside the iPhone 5.

Of course, these are all still rumors, and Engadget admits the timing isn't quite right on this one -- this is apparently an "Engineering Verification Test" piece from last March, which makes it older than some of the other prototypes that have reportedly leaked out. It's unknown whether this is the real thing or just another test unit.

But the wheels are clearly in motion on a new iPhone. And if the rumors play out as predicted later on next month, we might see not one but two new iPhones available for purchase.
