Multiple rumors regarding the 3G iPhone abound this week, all suggesting Apple is ramping up to an announcement and release of the updated handset sooner rather than later.  The Huffington Post is claiming that all three of the Apple stores in New York City were out of stock of iPhones on Tuesday, which Wired links with another rumor from Digg’s Kevin Rose who had Twittered that:

another person confirming iphone rumors w/me (high lvl VP at a big company that works w/Apple) - “it will ship in June w/3G and GPS” 

More grist for the 3G iPhone rumor-mill after the cut 

Rose previously suggested an “iPhone Pro” was in the pipeline, complete with 3G and dual cameras (for video calls).  So far, so speculative, but this chimes well with analyst Ken Dulaney’s recent revelation that Apple have placed an order for 10m iPhones from their Asian suppliers.

While there’s no confirmation that those 10m units were 3G iPhones - they could in fact be the existing model, with Apple preparing to launch in a new territory - Dulaney suggests that the order is for the company’s new model, and goes on to speculate that it uses an OLED, rather than TFT LCD, touchscreen.  That would allow the 3G iPhone to not only be thinner but more power frugal, helping offset the 3G battery drain that Steve Jobs was so worried about.
