In a lot of these free public wifi areas you have to accept their terms in order to use the service. In order to do this you must open safari and a page should pop up asking if you want to access the internet. Once you accept you can surf the web and check your mail.
i think that goes to open wifi network or your secure internet at home, so if you are using encryption at home that makes you not be able to get connected (for some reason) or it's a sort of IP conflict between your machine(s) at home and your ipod But i think it's the first one. are you using secured wifi at home?
When i go on the internet like my internet that i connect on the xbox 360 my laptop it works on those but not on ipod i connect but it wont let me surf the web or go on apps like myspace and aim what do i do
