I want to get the headset that makes the FM radio work on my 6230, but I have read that not all of them work. Which one do I need to get (Shay might ask you this for me)?

Also, as far as the MMC cards for the 6230, can I use SD cards too since they are interchangable in most devices, or just MMC? I have read posts that say only MMC and I have read others that say both are able to be used. Which one is correct?

Thanks.
