Your friends Sony is locked to the Orange network, even though T-Mob and Orange are under the same name now as EE the network locks remain in place (for the time being anyway) T-Mob and EE4G use same sims but Orange is different.
Your going to have to get your friend to unlock this for you, you will not be able to. Just get your friend to ring up and request this or got to http://explore.ee.co.uk/unlock
