any body there who's upgraded R1B to R1D or R1F ..... pls do let me know ... how to go about ?

is there a download available ?

I think most countries now have the R1D firmware available, and i have heard that theres R1F, though i think its rare. No you cant download the firmware, you will need to bring your fone to the SE Service Center in your area
