Word of a 2008 3G-compatible iPhone release didn't come from Apple, but that didn't stop the company's stock from climbing. The Cupertino company's stock closed on Wednesday at US$180.22, and climbed up over $184 late Thursday morning.

The news that Apple is planning on releasing an iPhone model that works on AT&T's faster 3G wireless data network instead of the slower EDGE network currently in use came from AT&T CEO Randall Stephenson. Although he confirmed a new model was on the way, he did not say exactly when next year to expect the release.

Despite its reliance on the slower EDGE data technology, Apple's combination iPod and smart phone has proven to be popular with customers. Compared to other cell phones, the iPhone offers an easy to use multi-touch graphic interface, easy software upgradability, and applications that many owners find easier to use.

The iPhone is currently available in the United States, United Kingdom, Germany, and France.

Apple's stock is currently trading at $184.03, up 3.81 (2.11%).
