I bought a Lumia 800 18 months ago when they were selling them off so not expensive and for me a brilliant phone. Last Monday it refused to start up, so I took it into the O2 shop to see if they could start it, they could not but would send it away. Apparently it was still under warranty, which surprised me. Wednesday I got a phone back, not my own phone repaired, not a refurbished Lumia 800 but a brand new shiny Lumia 930. To say I am chuffed is an understatement. Well done O2 you have a very satisfied customer.
