[NCLUG] Data Through Cellular Technology?

[Marcio Luis Teixeira]

Where can I find some information decent information about wireless cellular 
technology? AT&T's page (http://attws.com/) is overhyped and doesn't contain 
useful information. I was able to glean some good information about the 
various technologies from "wikipedia.com," but I'm not sure how it all 
relates to AT&Ts royal mess of tradenames.

Many years back I recall you could buy little PCMCIA cards that could 
send/receive e-mail messages on a HP100LX palmtop. I believe this was based 
on CPDP technology. Does this sort of service still exist?

On a similar note, suppose I have an existing cellular phone (an AT&T prepaid 
plan). This already has built-in text messaging, but is a pain to use on the 
cell phone. Is there anyway I could pop a cellular PCMCIA card into a 
computer and have it send/receive text messages via my existing pre-paid 
plan?

Any ideas or links to sites containing information would be appreciated.
