Ok i'll clear this up - from April this year you could spec 'Internet option' on your new 3 series or M3 (£95 option i believe). I specced it on my new car. You need an internet capable phone to use the function - the car displays the websites etc and you can browse using the i drive controller but the phone is what provides the actual internet connection.
This is different to the BMW 'online' and connected drive which come a s standard with all BMW specced with Prof Nav and bluetooth.
