Sony Ericsson K800i

One thing that doesn’t differ among the K800 range however is the restrictions placed on the handsets to restrict them to use on only one network, the one the handset was purchased on. But its never been easier to change that, with the simple use of an unlock code, the restrictions can be removed and the phone can be open to use on any mobile network. The best part is, unlocking a phone is completely legal and increases the resale value of the phone, and is usually free to do!
