It's an idea I had, but turns out they already have it (kinda) for Android. I want my network data all sent over SMS since I have unlimited SMS and not unlimited 4G. From a programming perspective, it should be easy as long as you know how to hook into the iPhone's networking and reroute the traffic. I could even write one that just does web browsing myself. There would have to be a server, of course, that acts on behalf of the iPhone by sending and receiving SMS and packets. Here is Smozzy, just a web browser: http://smozzy.com Problems are that it's for Android, and it doesn't route all system traffic through SMS, just web browsing. Is there anything like this I can download on Cydia for iPhone?
