A possibly leaked iPhone 4 prototype is getting plenty of attention because of its 64GB of storage -- twice as much as iPhones now being shipped, according to media reports.

The 64GB in storage is about twice the capacity of the top 32GB iPhone (News - Alert) 4. Industry observers believe the prototype is about one year old.

Media reports said that a technology blog, known as M.I.C. [Made in China] Gadget, was able to get a real but unreleased iPhone. It features dual cameras, an external antenna band, and lass-coated front and back panels.

M.I.C. Gadget reports on its blog that, “We are not sure” if it is the next iPhone.

“But we’ve just got our hands on an engineered prototype of iPhone 4, with 64 GB storage capacity. We tested it, and it is the real thing, no jokes here. On the back of the device, it has ‘XXGB’ marking, representing the unit as potential Apple (News - Alert) prototypes. However, we found out that the device is very similar to the lost iPhone 4 prototype bought by Gizmodo,” according to the M.I.C. Gadget blog post.

The blog post added that the owner of the prototype told M.I.C. Gadget he received it from someone “who has a small quantity of these prototypes. They are definitely leaked from Foxconn’s factory in Shenzhen.”

The owner of the prototype claims the next version of the iPhone will offer 64GB storage capacity to its users.

But other media reports contend that because it’s a year old, the prototype may or may not be an indication what Apple plans to release in future iPhones.

Yahoo News points out that Apple typically displays new iPhones at the annual Worldwide Developer Conferences, which are held in June.

At that point, there may be a clearer idea if an iPhone 5 is coming out, and what it may feature.

In other recent iPhone news, TMCnet reports that an award-winning movie director has found a new way to use the popular device: To shoot an entire horror movie.

South Korean film director Park Chan-wook used an iPhone 4 to shoot "Paranmanjang,” according to TMCnet.

The movie is about a man, who while fishing, catches a woman. "Paranmanjang," translates into English as a "life full of ups and downs."
