I am intrested in knowing how much does it cost to upgrade the firmware around the world. I got my n9210 from another country and I took it to the sole agnet here in KSA and the person told me it will costs $133. Another dealer charges $53.

I think both are excessive but sole agnet is surely trying to rip off people.

Alos , does anyone know what is involved in the upgrade process?

If you phone is still under warranty then it shouldn't cost anything.

I know that, the problem it is bought from another country.

I heard about nokia Club but KSA is not a participant yet. Also I heard someone stating their is a VIP club?

oh my god, that is just too much.
here in bombay, india we get it done for FREE or they charge a first time nominal charge of Rupees 75, i.e. US$1.5, thats all.
i think it would be cheaper to send it to india & get it done , only the time factor would be a problem i guess. ; )
