I've just bought my first BB 8700g here in Mexico City. I want to upgrade the OS from 4.1 to 4.2 but: I wanna know if I must download the new 4.2 version from my carrier (telephony service provider) that is "Telefonica Movistar" or I can use any 4.2 OS I can find on the internet?

I want to upgrade the OS but I dont wanna lose the movil telephony service.

Thanks to anyone who can help me.

You can use any carrier OS for the 8700g.
