Use Sprint HTC EVO 4G in other Carrier

[Aids82]

Hi All,
Happened that I have bought Sprint hTC evo 4G. I live not in the USA and want to use the phone in our local carrier. So the question is how can I unlock it?
I have read much of information on this forum also but it is still not clear for me what exactly should I do with the phone. There are a lot of actions described like:
1. get root access
2. unlock nand protection and so on

But which actions are required for me?

Moreover these actions are different for different versions of hboot and software.
I have a following configuration:
hboot: v2.10
hardware: 0004
software: 2.2

Help me please, explain what I have to do? Will appreciate if you give me links to instructions for my versions.

Thanks in advance, Alex
