When I went to upload pdf files to the Edge, I read the documentation which said I needed a SD card, which isn't included. No info about the card in the included help manual.

I also don't have a SIM card, and I don't even know what that is.

Does anyone know what type of SD card, and SIM, it takes, and where to buy one? They aren't for sell here at the Edge store. Thankx in advance. Aggie
