Here's video proof of one of the reasons the iPhone is such a unique device. Who can even begin crafting out an app like this for RIM's Blackberry Bold or HTC's Touch Diamond? iRetroPhone is an iPhone "native" all the way. Scroll down for some rotary phone goodness.

ObjectGraph, the folks behind this nifty little app, claim they will be making it available through Apple's upcoming App Store as soon as it's launched: "We are glad to announce our Retro Phone iPhone Application, iRetroPhone, and this will be available soon in iPhone's app store. It simulates a rotary phone in old days. Enjoy the realistic sound effects and animations," the team behind iRetroPhone says.

No pricing details are mentioned, but given that the company's core focus is to assist enterprises in designing visualized, cost-effective, and leading-edge solutions that help deliver superior business results, we can guess iRetroPhone (just like Apple's set-top-box) is the company's "hobby."

Of course, the app doesn't have to be free, even though it's more artistic than it is useful. As some of you already know, developers that charge for their apps (if they are released through the App Store) get a 70 percent cut from sales, while Apple retains the remaining 30 percent for service maintenance. Either way, it's most likely going to be cheap - Apple is allowing developers to charge as little as a dollar for an app.

There's more! ObjectGraph claims that once their app is out in the wild, they will be releasing "a skinning specification for creating custom skins."

Established in 2004 with the main purpose of helping enterprises build custom software solutions for changing business environments, ObjectGraph has successfully implemented a wide range of solutions including complete end to end student loan consolidation system, e-signature, bulk PDF printing and stapling APIs, shipping integration with FedEx and USPS. The company also has some experience in travel and jewelry industries.
