I just purchased a Palm TX and I'm a little paranoid about people being able to access the personal information on my Palm in a public wi-fi hotspot if I'm using the web browser or sending and receiving e-mails. Do I also need a firewall on my Palm if I already have Symantec Antivirus for Handhelds installed? If so, what are some firewall vendors for Palms? I can't seem to find any on the web.
