[mysteryman]

Currently locked to three my question is can it be done remotely using codes? If so wheres the best place to buy one from? If it can;t what do i have to do to get it unlocked?

As far as im aware can only be unlocked by your network considering the phone has just come out they will charge about £115. Due to you being in a contract, unless its bought from someone in that case i dont think they will even do it.
