sd card for arduino wifi shield

what is the maximum size of sd card i can use for arduino wifi shield?

I don't know the answer (although I would guess the maximum for a non-extreme SD card, so 32Gb) but if you were thinking of buying the wifi-shield be aware that it is now obsolete and would require a firmware upgrade if you wanted to use it with a current Arduino - a right PITA from I'm reading on the web!
