The 6630 CANT NOT be unlocked at the moment, there is no method or way to unlock it other than through the Network you are supplied by. They are currently working on a unlocker but the 3G software is tied into the unlocking process now.
So no unless you go to the Network supplier then there is no way to unlock the 6630.
How I am I so sure, a friend runs a phone shop and I have the 6630!
