Unlock codes

[paw83]

Hi All... T-Mobile retail employee here, just sold my Nokia 6280 on ebay cos as we all know they're poo! Thing is buyer has asked me if I can get the unlock code.... i know I can get it by paying for it, but I was wondering if any of you guys in CS or even technical can help me out with it? Just look at my account and you'll see I'm staff (12 lines is an unhealthy amount!) If you could let me know if it's possible it's be great,

Many Thanks,

P
