That's what I had to do after I spent over an hour dealing with 3 different people of the chat option. It came through after about half an hour.
Ive just requested it to be unlocked on my o2 account online. Easy just enter the imei number and send. Mind you I dont know how long it will take to come through.
Another update on this. The phone does come locked to O2. Took me about an hour dealing with O2 to sort this but it can be done for free at least.
Just to update on the battery, with the stamina mode on the battery drops about 1% an hour so for light users this will last 2 days. When being used for web browsing etc the battery does drop pretty quickly and if if was my main phone it might not last a day. Overall its a great buy at £49 if you are a light user.
I made an order but had no confirmation email or dispatch email but the money for it is showing as pending on my bank account and there's no sign of the order on my o2 account either
