It's all over the internet. It's not official, but it is everywhere.
T-Mobile have the iPhone in Germany.
O2 have it here in the UK. Let me be the first to say...Awwwwwwwwwww Yeahhhhhhhhhhhhh. O2 is the carrier I was hoping for, so as far as I'm concerned, this can only be good news.
News Wireless are sticking to their Vodafone story, backed up by some generic files in the iPhone as shipped stateside and their own unidentified sources, but owing to the unreliability of some of the other info they've posted, such as dates for the announcements and the unlikely 3G support, we can probably ignore them.
That said, they may be right that "O2" means "Carphone Warehouse" - a virtual network running on O2 is operated by the retail giant - however, even if this is the case, I imagine an O2 version is a must. Since O2 are the ones who'd have to upgrade the systems, I'm going to guess they'll want a piece of the pie.
And O2? Why not throw some iPhone love Tesco Mobile's way?
