I have a 5500 & 5600 (both off of ebay). When I insert a wireless card into the 5600 (Sharp ROM 1.32), I can find wireless networks (using Kermit) but don't see any way to connect to any of them. When the card is inserted into the 5500 (Sharp ROM 3.10), I get a connection icon in the tray, and a connect dialog in Opera. The previous owner of the 5600 claims to have used the card, but he did have a different ROM (Zynergy) installed.
