Sure, but that's B stock, plus more importantly I don't particularly like the over-simple styling of the P4350. The soft touch finish of the Wing is much better.
And it comes with the headphone/power splitter in the box as standard.
Well, in this case, 'b stock' means 'badly danaged packaging', and it's you who made the original cost comparison to eXpansys, not me
Besides, I think shipping to and from the US for warranty service would be prohibitive, as you'd need an export certificate to avoid incoming duty again etc etc, not even considering you've got a subsidised, locked, carrier supplied device without being a t-mobile US customer so they wouldn't accept a warranty return anyway unless you could trace the original subscriber and validate the IMEI.
So if you prefer the US Wing, great, pay mopre and get one form the US with no warranty, but if you want a cheaper device and a UK warranty, get the b-stock one from expansys or shop around...
