Cyberwaste

I have a plan. I want people to let me know if it is feasible. With all these new xG phones (Droids, Smartphones, etc.) I've noticed that the internet is a handy tool to, well, have on hand. Especially while on the go. I'm also not a fan of paying into corporations. Many of these phones have apps that basically turn your phone into a modem. You can also get Skype apps and such for your phone. I was wondering if it were possible to get a modem app so you can latch onto wi-fi without paying for the internet and use skype to call people (on skype) without paying for a phone service. Let me know, because I think it's an intriguing idea to take an old phone, keep it and make it into a skype phone. It'd be fun to at least try.
