Here is a link to the GoPro Firmware upgrade, you can now use the 4GB cards for almost 2 hrs of video.

They have also introduced the new HD Cameras!!!

I have not ordered my first batch of HD's as I still have 6 of the SD's left.
I will be ordering a batch of 24 HD units at the end of the year, in the meantime if you want one, I can order singles too!
