I read somewhere that the "Ask to Join Networks" feature makes your ipod touch automatically join any unprotected wireless network it sees. It's not working for me though. Am I doing something wrong or was what I read just not true? Also, if it doesn't do that is there an app that will automatically join any unprotected wireless network it sees? I don't want one that just scans because I can just hit refresh over and over for that functionality. Thanks a lot for the help!
