Unlocking Blackberry

[Neeja]

I work for Vodafone and won an 8310 curve a few weeks back. It's going to be fleabayed, and I'd quite like to unlock it first. Unfortunately, going through official channels in work has brought up a blank as it's not technically a Vodafone phone as it wasn't purchased from us, instead it's a Blackberry phone with Vodafone branding and software. As a result, Vodafone can't/won't unlock it.

I recall someone a while back saying they have unlock codes, anyone able to get me one if I supply IMEI? :)
