Intel Confirms Atom-based Larger iPhone (Mini-Tablet)?
As part of an Intel event for the 40th birthday of the semiconductor company at Munichs BMW World, Germany managing director Hannes Schwaderer confirmed today what has long been a rumor on the Internet: namely, that there is an iPhone with Intels new Atom chip. The device is slightly larger than the current version, Schwaderer said. That is not, however, because of the Intel chip, but because of the larger display used in the new iPhone.
He goes on to say that an upgraded version of the current form factor of iPhone would also exist as a 3G-model.
While Schwaderer calls the larger device a "version of the iPhone", it seems clear that it refers to the rumored mini-tablet device. Some rumors have suggested that it would be introduced at WWDC.
