In about 2 hours Steve Jobs will take the stage in the Apple flagship store in London on Regent Street to most likely unveil the iPhone details for the UK and maybe the rest of Europe.

Update:
O2 iPhone official for UK

UK's Pocket-lint reports that Steve Jobs is in London to meet with the press at 10am in the Apple flagship store on Regent Street. Obviously the store is closed to the public at that time.
The store will reopen at 4pm and will be open late today until 10pm reports Apple Insider. The question is whether or not it is worth while to stand in line to be one of the first in London to buy an iPhone.
We will bring you updates about the Apple iPhone announcements as they hit the web.
