CEniffer 3.2 is here:

looks a bit gay to me
Airscanner's sniffer is fantastic, might be worth getting a cheap CF wifi card that is supported by it if you are serious about sniffing on that pda.
There are a couple of commercial sniffers around, airmagnet and one i forget the name of.. but they cost big bucks. like thousands
The other option, one i'm looking into atm is installing linux on the pda and using kismet. i've used kismet on a laptop b4 and it's awesome.. just found out tonight that they have ported it to ARM so i'm keen to try it.
Final option is coding your own. I'd really like to do this, would be great to include wep cracking, but i'm not sure how much low-level coding is required. Hopefully there's the right C libs around................
