I'm using Vodafone 6630, That's Vodafone 3G network. Is that a new network? If I want to unlock it, is it a new MMC code? I am wondering......For This.....

It is not possible to unlock the Nokia 6630 at the minute, unless using an Unlocking Clip.

Bear with it though, "flashes" are steadily becoming available so have a chat to your local market man.

Hope this helps
