O2 Ireland - how do I unlock it?

[SAFC1BeerMonste]

Hi guys, I have had a look at the calculator but there is no service provider listed ofr O2 ireland, which one do I use because that is who the phone is locked to.

Please help, O2 Ireland is no good to me at all.

Please forgive me if this is in the wrong section.
