So I'm way too cheap to pay $20 a month for unlimited SMS, so I've been using a Ymail account for push messaging and sending SMS through gateways. Is there any alternative for free SMS? Like through a Cydia app with unlimited free SMS that would make things easier? My only problems with email is that I have to look up each persons carrier and create a seperate email address with it. That and I just get notifications for email and can't tell the diff between that and my SMS. Any suggestions? Or anyone interested in making a SMS looking app that runs off of a Ymail account?
