As you might already know, Nokia have been shutting down their online stores, and it looks like the UK and USA stores are the latests to be shut down following in the footsteps of the French, Finnish and Spanish stores to name a few.
If you try to go to the store, you are just presented with a notice that it’s no longer there, so you will now have to purchase your devices via other places like Amazon, network providers and other phone/electronic stores.
It seems that the only official Nokia online stores are now in China, Portugal and some places in South America.
Personally I think this is a bad move, I have always purchased my devices direct from Nokia as I wanted to be the first to have it, but it looks like that will almost never happen again!
