Keep in mind this forum forbids spam about unlocking so my advice is to not pay unless it works with a sim from your carrier.
You didn't tell if this had an active sim. Video at http://www.youtube.com/watch?v=19OEA9zJ0jE
Looking at buying an Xperia T but the person tells me that when you switch the phone on, it comes up with 'no network'. He says that the phone needs to be unlocked. Does anyone know if this is possible? Don't want to buy it if I want be able to do anything with it!
Many thanks for your responses!
