Unless you have some reason to avoid sharing it, you should let us know what you did so we can properly appreciate it and ideally give us a tool/app to do it ourselves and start making use of it! Explaining *how* you did it is not required, although I personally nearly always do so; it's a good way to build trust.
Having 10 posts will let you create a thread in the Development & Hacking forums, which is really the proper place for announcing a successful hack, but there's nothing terribly wrong with posting it here instead.
Depending on how good your hack is (interop-unlock? full-unlock? bootloader-unlock? arbitrary code execution with full trust?), whether it's specific to Nokia phones or not, and what it requires (special hardware? a particular regional ROM? hard-resetting your phone?) we may start using the hack immediately; any time you sit on it is time we can't even get started. So, let us know what you've got!

Do not private message me with questions that should have been posted on the forum!
Not only are you wasting your time - I'm not going to bother writing an answer to such a question for only one person - but I will probably block you from PMing me in the future as well.
