Ken Dulaney, a Gartner analyst has divulged to the iPod Observer that Apple may have already placed an order for 10 million 3G iPhones. Mr. Dulaney is aware of this based on the rumors he his following in Asia.
Mr. Delany also goes on to speculate that the 3G iPhone will also use organic LED's allowing the device to be thinner and have a lower consumption. This comes just days off of Kevin Rose's declaration that the 3G iPhone will have a built-in forward facing camera, possibly for video chatting via an iChat like client.
Will we see a new iPhone in a "few months"? My bet is the announcement will have to be at the WWDC this June.
