Lost/Found K530i Sony Erricson phone

Hi All
I have found a sony erricson K530i phone and it is locked to Orange France. The problems i found in it:

* I inserted my own SIM and it didn't work and when i reinserted the old SIM, it asked me the PIN code and after three unsuccessful tries, it gets locked and asked me the PUK which i undersand more related to Service Provider and only service provider can give that too me.
* Second problem is that it is in French language and i dont understand it.

What are my options to use this phone as a world wide phone? If i can be able to to unlock this phone, may i be able to use it in North America?
What are the options i have interms of unlocking this phone?

Thanks in advance!

Your only options, are to turn that phone into your local police dept., or return it to the wireless network that the phone is registered to, so that they can find the real owner of this phone.

You will not receive any unlocking solutions from CPF, for a phone that was either lost or stolen......
