my iphone too hv problem with public wifi.

I can use it with my wifi at home but when was in public, can detect wifi, selected

but can't online..

why? pls help!!!!

are you sure that signal you saw is not locked? some signal showing like its free and available but it actually not... try to connect em with other device....

For a normal free wifi area like coffee bean, sbucks, etc...etc... no prob at all....
