Question for 7D and 60D users

[Kombi]

Sorry this is a weak question, I keep reading and rereading and have confused myself.
So instead of rereading again. Figured I'd just ask.

Do either the 60d or the 7d use BOTH CF and SD cards?

It looks as though 60d uses SD and 7d uses CF, but I thought I read a review somewhere that one of them could use both.

Thanks

While your here.
My t2i numbers files up to 9999 then went back to 0001, do either the 60d or 7d save files past 10k?
