Singapore Expats

Hey there gurus out there, do you where can I get this phone of mine unlocked and how much I shd be paying for it? It's a quad band MOT SLVR L7 currently locked to Cingular. Such a shame MOTs aren't like Nokias where u can just punch in a code to unlock it.

Appreciate the help! If you can recommend a specific store that would help. I just don't wanna walk into SimLim without a store already in mind.

Thanks!
