HTC Hero unlock, no company fee?

I have a HTC Hero, which I have bought from a friend, who was getting a new phone. I can't get the tele-company to unlock it (unless I pay 70$), and now I'm thinking: Is there any chance I can unlock it from home, via a cable or something :)

Thanks in advance.

Free unlock code is not possible to get for this HTC HERO phone,you need to pay to get unlock code.Then if you use software it may damage your phone.So better use unlock code to unlock it easily.Softwares are easy for professionals.But unlock code is easy for everyone.Which country network it is locked now?Get unlock code from the site Unlock-zone.com and unlock your HTC HERO easily.
