Rumor roundup: A new iPhone on Monday?

Apple will hold its World Wide Developer Conference event in San Francisco June 8, and speculation has mounted over the past several months that the company will use the venue to unveil the latest version of its mega-successful iPhone. Such a move would dovetail nicely with the company's modus operandi: Steve Jobs unveiled the iPhone 3G at the event a year ago, shortly before the device went on sale to an apparently touchscreen-hungry public (Apple sold a whopping 6.9 million iPhone 3Gs in the three months after its release).

[1]Thus, the possibility of a new iPhone unveiling is clear, and there is plenty of circumstantial evidence to support such expectations. Indeed, tech celebrity Walt Mossberg of the Wall Street Journal seemingly confirmed a new iPhone his review yesterday of the Palm Pre: "Whether the Pre is better than the iPhone depends on your personal preferences, though I'd note that the new iPhone to be unveiled next week will have lots of added features that could alter those calculations," Mossberg wrote.

Nonetheless, the level of noise and buzz is such that it's worth recapping the rumor and speculation from the past several months that appear to show a new iPhone in the offing.
