Hmmm - the store I popped into in London advised they can only sell the phones with an EE contract (I'm with O2, but apparently that's a no go.) One of us has been misinformed...I wonder who? :/
Both stores i called said they were available on any network. I got to admit they were just small stores in shopping centres, but they quoted enough to make me think they knew what they were talking about.
I really hope its not just EE.. The missus is sick of me talking about the phone and having to wait another 6 months for it: i would be just intolerable lol
