Unlock sony ericsson x10 mini pro?

[wiiiiii]

I've just bought this phone (UK) but it's on vodafone and i need it on 3, can anyone tell me how to unlock it for free? I can't find anywhere that'll give me the unlock codes!
Some people must have unlock codes that they've bought in the past though? Someone help me PLEASE!

You can not get the code at free of cost.You have to pay for the unlocking service.I found the unlocking solution here Online GSM Unlock.com - Unlocking the Sony Ericsson Xperia X10 mini mobile phone at cheap price. Through this you can unlock your mobile easily
