Hi Trace, all cards over 2 gb are SDHC. They will work in all devices in which 
SD cards did. Also, when looking for a card don't only look at capacity, but 
class rating. Where a class rating isn't given in an advert, as in a lot of 
Sandisk adverts on Amazon, for instance, it's because they're a lower class 
rating. The class rating is how fast the data writes to the card, class 2 2 
mbps, class 4 4 mbps, class 6 6 mbps, and class 10 10 mbps.
                    John.
