It's much like how your wifi laptop works... Almost...
"can these forward my emails to the handheld?"
Sort of. Forward it to your webmail account (hotmail, yhoo, gmail, etc.
If I have a Palm T/X that has the software and for WiFi and email, can I send/receive emails using the device, without having to pay for a monthly service for the handheld?
I have AOL as well as corporate email, can these forward my emails to the handheld?
