the nokia 6260 supports rs mmc but the interface is compatible with the normal mmc!
has anyone tried putting a normal mmc card in it?
is there enough space?
the rs mmc are quite expensive and offer only a max of 128mb
if i can put a 1gb normal mmc card i will buy the phone, else i don`t know

A full-size MMC will not fit. Only RS-MMC cards.

At least ATP has a 256MB RS-MMC:

As does TwinMOS:

i tried it and it bent the rs mmc card holder so dont try it,i manage to read the card and close the back cover in result of bending the back cover also so i took it back to where i bought it and told them that the phone was faulty and got it changed....sshhhhh dont tell anyone!!! SO DONT TRY IT!!!

I believe that www.ebuyer.co.uk has a 512mb rs-mmc for circa £70
