in my camera to be able to use my 4gb SD card that I already ahve?

if its a 4gb SDHC card then I'm sure it will not work, if its a SD card then it will work as long as your camera works with 4gb cards, some old cameras will only work with 1gb or 2gb or less

any idea how much memory the cannon 300d will allow?
