SDHC for fake dstt

well, the build of my dstt show that it's a fake and i've known for some time.
the question that ponders me now is: will it be able to use microSDHC?
this is just to assure myself that it can, and i'm starting to run out of space on my 2GB -.-"also, is it the firmware that effects this? the hardware? or both?

The card itself is just a fake/clone. Yes it will be compatible with MicroSDHC cards.

thanks for the info.
can i also ask what's the difference between regular SD and SDHC?
is it to do with size, performance, or some other thing?

SDHC = Secure Digital High Capacity. The name says it all.
