Hi, I'm trying to unlock my Blackberry Curve 8520. It's set to Orange but I want it on 02.

My IMEI number is 351505057010228
My PRD is -30001-028
Not sure where to find my MEP code (Sorry)
I think it might be MEP-07723-004 or MEP-07321-002?

If you could find out my unlock code I'd be real glad.
If not then I'm sorry from taking up your time.

P.S. Would you be able to email it to ladydiva11@hotmail.co.uk please?
