Signs are now pointing to a January 2007 release, most likely at a newly expanded Macworld 07. Think Secret's insiders claim Apple is shooting for the stars, expecting to ship 25 million iPhones in 2007 alone. If true, this is a bit of a surprise since Motorola's incredibly popular and more widely appealing RAZR has taken over two years to sell 50 million units. Perhaps most interesting of all this rumor rehashing is Think Secret's report that Apple's exclusive Cingular contract for the iPhone only lasts into the middle of 2007 - meaning that other carriers could pick it up and finally get in on the as-yet awkward iTunes phone action.
Again, you know the drill: this is all hearsay from 'anonymous insiders,' so do what you will with it.
