I found a samsung galaxy s?

I found this phone last week and I was wondering how can I unlock it?

Hi if you want to unlock your samsung galaxy s mobile from network provider then code is the best solution to unlock it ..You can purchase code from online providers like Mobile-Unlocker.com for reliable cost .You first check that whether the code is available for your country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ...
