I purchased my phone and haven't signed up for nay BB services yet, just the phone/sms/etc. I notice I do not have an icon for a browser on my menu anywhere that I can see. Is it downloaded/added only after signing up? Yeah, I'm fulla questions today, just activated it! ;)

You will need the BB Data Plan to get the browser icon, push email ,etc.
