AIM on Palms...

[DanL]

I'm pretty sure Symbol makes Palm attachments or special Palms with wireless networking capabilities... try checking them out

It's apparently a 802.11b card that works in your CompactFlash port. It's designed for PocketPC's, but on Symbol's wireless section you might be able to find something for Palms

A quick glance at Palm's accessory page reveals that they sell both modems and Bluetooth connectivity devices. For 400 to 500 bucks, you can grab yourself a Bluetooth access point. Didn't see anything about 802.11b, but you could try Googling it and see if you come up with anything (if I found these things by just clicking a few links on sites, Google should come up with plenty of hits for what you want).
