I was looking at the MyWi app and i was so happy that the app would give wi-fi to my device anywhere but when i read into it more and found out that it doesn't work on ipod touch, i got enraged! It's because a carrier is needed for this tethering to work.. Is there a way to get wi-fi signal on ipod touch wherever you go for free??? someone please give me your ideas... if its not free, what is the cheapest way? I need some experts to answer this question. It would be much appreciated.
