AFTER you have followed earlier instructions to delete Gtalk (Options-->Advanced Options-->Applications-->select gtalk and delete), then pull the battery and do a reboot, the icon should disappear from the home screen.
If not, then hide it (while over that icon, hold down ALT key, click trackwheel and select hide icon).
Ohad, it seems to me that you need someone like your customer service rep to talk you through basic setup of your Blackberry and do as earlier advised and confirm you have a Blackberry Data Plan from your carrier.
