I just received a Kingston 2GB rs-mmc card and while the phone (a Nokia 6680) and the card reader read and write the card just fine, the 770 says "unformatted or damaged card".

I let the phone format it in case it was not ok, but the result is the same.

In the control panel I can't format the card because in the tab it says it's damaged and everything else is disabled.

Any idea?

Could it be the 770 reader is not 100% rs-mmc compatbile?

Edit: I'm runninng non-beta2006 and I don't wish to downgrade unless it's proved it will solve the issue.
