So people are now throwing around the last week of Jan./ first week of feb. As when the phone will launch. But there hasn't even been an announcement for an event, I don't very much think apple is just going to send a press release announcing the iPhone in verizon, jobs is going to want to sell it up a bit, especially since for the past two years verizon users have been told time and time again by verizon how much better android is.
Then there must still be some lead time from the press event, maybe a week in advance, I doubt they will launch same day as announced, they want people to line up over night and allow news reporters to go out and cover the launch.
And then there also needs to he some lead time for press to go the press event, they can't just say "hey, come to Cupertino, we have announcement today", so again maybe a week in advance as well. That means for a late Jan launch, the announcement for the press event needs to come in by the end of next week, and for first week of feb. It would need to come within 2 weeks, and that assuming a very quick turnaround.
