- They are pre-order, so you'll receive it upon official release
- Unless you buy from US retailer in which case you will have no warranty (unless you have an address in the US of course )
-Make sure it is "unlocked" for all carriers
The good points if you buy from a UK retailer is that you'll be able to use any carrier if the ebay page says that the Lumia is unlocked. You'll have a 2 year warranty usually.
I bought from France and am waiting for it to arrive. Only it may be available only between late may / early june, so have to wait until then.
