Hi,
I checked through the thread on MMC and the max working MMC posted there is 256MB.

I am thinking of TwinMOS 512 MB MMC soon and wondering whether this is compatible,

Anyone has any success using 512MB MMC on 6600? Care to share on the brand too?

Thanks.

You didn't search the Tested MMC cards thread enough i guess or at all for that matter.There are two people on the first page of the thread saying that they've tried 512 MMC's.Thread closed.
