Does anyone have experience with the s56?

I have been doin a lot reading and searchin on the internet to find a way to unlock the siemens s56. From what I undesstand it can be done without cables. The IMEI number is need to create an unlock code which can be then entered in to the phone in the *#0000*xxcodexxx# format. So I have spent my time trying to find some kind of software or algorithm to create the unlock code, but it seems that no one has come up with anything yet. If anyone has experience with this subject, your help would be appreciated.
Thanks,
Tom
