Thank you for your answer.

I am from Greece but i am not in Greece right now. I am working as a physician in United states.
Can you please describe to me the unlocking process from the begining step by step?
If this doesn't work what is the alternative process?
If all these measures do not work, is there any other place where i can go and fix it? I can go anywhere in chicago!!!!!!!!!
Please help me! Is the phone that i was dreaming and now it doesn't work.
I don't think it is defective because it works fine as pocket pc.
