Can we use RS MMC IN PLACE OF STD MMC

can we use it in 6600
in coming 9500 etc

and one thing more my card reader is unable to read RS MMC

An RS-MMC works with an adapter to make it the same size as a "regular" MMC.

Any device that handles MMC's should handle RS-MMC in the same way (you just need the adapter).

it should be able to read using the adpater ..

i have use the adpater but stll it don't work on card reader.
