Reliable, cheap unlock for W610i?

I bought a W610i from Orange, and am now living in Russia, where I need to unlock in order to use a Russian provider. Orange want to charge 20 quid for the unlock.

Is there a cheaper, reliable unlock service? I've tried unlocking with SETool already and nearly destroyed my phone. Looks like doing it for nowt is not an option, so I'd like to find a cheap, reliable unlock method, if one is available.

Ta very much
