not trying to be a ***** but this realy should be posted in a diffrent forum. I dont realy know all that much about pda firewalls but you should only need an antivirus if you are planning on downloading stuff onto it from the net. Sounds like a dumb answer but if you think about it : What are yoiu going to be doing with it? just surfing webpages.... dont worry about av. Actualy downloading and running programs from the net ... yea you'd better have av. I have no clue about the firewall situation though. Hope you find the answers your looking for
