Sorry for such a fundamental question, but...I'm at a hotel and I have no trouble signing my macboo pro into the hotel's wi-fi, which requires a password. When I try to do the same with my iPhone4, it "finds" the hotel's wi fi and gives me an opportunity to enter the password. When I do that, however, it doesn't seem to go through and I cannot "connect." I've had no problems hooking up my iPhone to "open" commercial wi fi spots where no password is necessary, such as at Panera Bread and similar locales. So, am IK missing a setting or two somewhere? Thanks!
