I've just ordered one for £365.52 over the phone. I have an iPhone on O2 that the missus uses and just dialled 202 from the handset, went to upgrades and spoke to a lady who sold me the HD2.
The only downside is they are on low stock and she quoted 3 to 5 days for delivery. Worth waiting though for a sim free HD2
I also have an Orange contract sim that I am using with a white sim free Hero at the moment, I assume with the HD2 being sim free I will be able to put my Orange sim straight in it?
Just need to sell the Hero now, will have to put it on the classifieds
Cheers.
