Unlocking a cell phone is whats done to be able to use the phone on another carrier or multiple carriers. Most phones are carrier specific unless unlocked.
For example you can't take your AT&T phone and go to Verizon unless you have it 'Unlocked'. This doesn't work for all phones by the way. You need to be sure that your unlocked phone will work on the new network. Therefore you need to know if your now unlocked phone is TDMA or CDMA or GSM compatible with the new network.
Hope that answered your question.
I see that you are UK based.
Please note that the previous comments are based on US information. Unlocking still means gaining access to the phone software to allow it to use another carrier. I'm not positive what carrier protocols are used in the UK.
