Default Nokia 6700 - unlock it now for free .. ?

I have Nokia 6700 locked to Telenor Serbia which I plan on giving to my ma' cause she needs the camera phone for some stuff, but I cant seem to unlock it. I dont wanna waste a phone in perfect condition but these are the problems:

1. Telenor serbia cant give me the unlock code (they are retards)
2. I cant pay cause many services online still ask for 40e for unlocking this phone which is ridiculous
3. It's already "without any value" phone but should be useful to mom, and even If I could pay 5e for unlocking, I wouldnt out of principal

Is there any way to unlock this with something .. ? software maybe ?
