Wifi is so much faster than most 3g connections for my phone. The only place I've seen my phones 3g connection being as 'instant' as wifi was in London. Also using 3g uses up a lot more battery than wifi. Also it could be handy for giving the pw out to others (easier than reading out a long random password. Especially if there's an error and have to read out and retype the whole password to your friend)
