what SD card?

Has anyone upgraded their SD card? I'm looking into this currently and was considering a 4GB ADATA SD 150x card. Does anyone know if this would work in the Pin 570?

Many thanks for any advice.

Cheers Stu.

I managed to get a 4GB SD storage Card which does every think I want it really changes the PDA from a SAT NAV to a very useful bit of kit I've got laods of photos uploaded which is ideal when showing the family. Load of music and a few audio books. Highly recomend the larger card.
