Early last week a case manufacturer posted images of what purported to be a case for the iPhone nano. Case manufacturers have long been on the front line of Apple product leaks, and this image certainly caught our attention. Then this week someone anonymously provided MacRumors with a photo (seen below) of what looks like a presentation slide showing the nano alongside its big brother.

These two pieces of information, the case release and the anonymous photo, are by no means proof of the current existence of the iPhone nano, but they do raise interesting questions.  Is Apple working on a smaller iPhone to sell alongside the iPhone 3G?  Will the iPhone nano be a smaller, but full featured version of today’s iPhone, or will it have feature cuts in order to make it a $100-range handset?  Is this all just total B.S.?

An examination of the screen-shots of both the 3G and the “nano” in the image above show the icon’s labels appear alternatively in English and another language (French maybe?).  Also, many have proposed that the iPhone nano would not have 3G because of size constraints (and in order to sell for as little as $100), but the image shows the 3G symbol along the top of the screen of the nano.

The “evidence” thus far isn’t exactly probative, but it’s something we’ll keep our eyes on in the weeks and months ahead.  At this point, we have more questions than answers and remain highly skeptical.
