Well here’s a mega bargain if I did see one. Entering the prices of the almost disposable and certainly back up phone, Carphone Warehouse has the Quadcore Nokia Lumia 530 at an amazing £39.95! However, as Tom Warren corrects in the comments, this is for a “Pay as you go Upgrade”. Brand new on pay as you go, it sells for 69.99. Still good value.
If Carphone Warehouse continues their usual tradition, their handsets are usually unlocked.
