Hi,
I have attempted to unlock my mrs's Nokia which is locked on O2 quite a few times. The 1st was through the free O2 service after 12 months old, but came back as failed. Then I have tried a few times through the O2 £15 service. The last time failed as the credit on the phone fell below £15 needed. Unfortunately the pay and go go go deal only has 500mb data therefore takes a £1 a day for extra data. Because it can take 30 days to unlock, I think another option may be cheaper!

looking on eBay I see a seller listing this service: [Only registered and activated users can see links. ]

Do you think this will work and is safe giving over the phones IMEI code?
