Firstly i'm sorry that i join your discussion wiht my poor English skill.

I have read your discussion completely about how to IMEI changing. I can give you an example why a person really needs to do it.

I work in SSSR. Last year i have been to Turkey. At that moment i stayed to use my gsm (N97) and there is no way to use without registration your gsm, because of laws even you bring it with you. I have registered at that moment once.

So, it was last year happen.

And now Nokia published the new version of Nokia which is N900 named. I bought n900 this year and i came to Turkey again for spend my holiday with my parents.

It seems everything is ok but no. So, I bought this gsm in SSSR and i payed TAX for use it in SSSR. But there is a law here in Turkey which you couldn't register again a new mobile even you bring with you in two years.

What should i do if i need to use it here in Turkey?

I'm not thief as you described.

Even I payed completely for it to use in SSSR. But there is no way to use it here in Turkey without registration and there is no way to register in two years 2 gsm(s) to your passport.

I think that could be a reason to change IMEI and to use it or am i wrong?
