It provides the best instructions and easy methods for unlocking your mobile phones..........

try to do by following method
Warning: Do not enter any wrong unlock unlock codes on your Sony Ericsson K550i mobile phones. If you enter over a certain amount of wrong unlock codes on your mobile phone, your phone may get hard locked and sometimes become unusable.

1 - Switch ON your Sony Ericsson K550i mobile phone without any SIM Card,
2 - Press the left arrow key/button once,
3 - Press the button * twice,
4 - Press the left arrow key/button once,
5 - The message "Personalize with MNC2" will appear,
(or you will have displayed an unlock menu, select the lock you want to unlock)
6 - Enter the Unlock Code.

If your Sony Ericsson K550i mobile phone does not have a left arrow button/key(e.g. Sony Ericsson W950i) and on a few phones(not all) that have a "JOGDIAL" you must press the "down arrow" key/button instead of the "left arrow" key/button for step 2 & 4. We mean by "Down Arrow" to direct the Jogdial down! In the Sony Ericsson W950i and some other models, the down arrow button/key would be located on the side of the phone.

its to easy dude just take a glass of water and put your mobile into it and add some sugar also and start stiring after five minutes just restart your mobile phone if the spot is still appearing so through your mobile into dustbin

The best you can do is go to a phone shop and buy a cleaning set it often removes scratches.Or just buy a protective cover.
