Compact Flash Wireless SDIO Vs. Wireless Compact Flash! Dell Axim X51?

SDIO vs. wireless compact flash! Dell axim x51? - compact flash wireless

Well, I need to know. I am interested in allowing something that I connect to a network on my Dell Axim X51 (416 MHz) with Windows Mobile 6. I have two different ways, either with a Spectec SDIO card or a Compact Flash Amibcom. I'm confused, but when a CompactFlash card is better, or SDIO card. If you have an SDIO card, which I can not do my SD card. I have only 1 slot for SD card.

Thank you!
