Is there a step by step guideline on how to unlock my samsung phone SGH-F480T please?

Hi,after getting codes for your mobile follow the instructions about how to unlock your mobile..
Warning: Do not enter any wrong unlock unlock codes on your Samsung SGH-F480 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.

Method 1:

1 - Switch ON your Samsung SGH-F480 with a NOT ACCEPTED SIM Card.
2 - Samsung SGH-F480 will ask for "Password".
3 - Enter the Unlock Code.

OR (if the Samsung SGH-F480 shows "Insert Correct SIM Card")

Method 2:

1 - Switch ON your Samsung SGH-F480 with a NOT ACCEPTED SIM Card.
2 - Don't bother about what's being displayed on your Samsung SGH-F480.
3 - Compose : #0111*CODE#.

NOT ACCEPTED: We mean, to use a sim card from a network other than the network your Samsung SGH-F480 is locked to.
CODE: Its the unique Unlock Code for your Samsung SGH-F480.

If method 2 does not work, you can try method 2 again but this time without any SIM card on your Samsung SGH-F480.

Each Samsung SGH-F480 mobile phone has an unique unlock code.
