IMEI unlocker or code generator??

Well at a loss for where to post this.. I thought in here could be a good start..

Hi Guys and Gals!

I aquired an iphone4 just recently.. its not active.
I tried all kinds of stuff on the internet to get it to unlock so I can put it on my provider but no luck.. it just sits at canning for carrier.. I was told it needs to be unlocked get it to do what im wanting it to do.

My question in regards to this is.. Is there a FREE iphone imei code generator out there to unlock this puppy.. There must be a brute force code creator that uses the imei number to create the code?? No? Yes? Kinda like a code generator that opens computer software to get a license or glitching old school sat cards? know what I mean?? or is it just a code that is put with the imei number and only certain people can access cuz they are special? LOL no disrespect just trying to figure this out..

I cant seem to find anything that looks legit.. its almost like the days of getting sat cards unlocked.. you need to know a guy, that knows a guy, who's brothers cousins doctors gardeners brother knows a guy.. to find this out...lol

any hints of direction would be appreciated if anyone knows anything... There is so much info on the net these days its sometimes hard to find legit info.

thanks in advance!
