"There are lots of reasons GSM won't/is hard to make work. What are the options? As more and more carriers in the USA provide wifi-dongles that are connected to 3G, maybe it's better to just do that, and move off making calls directly from your phone completely?" This is an obvious approach, and the one that I originally pursued when I became worried about baseband exploits, security and privacy. I was looking into using a "samsung galaxy player" (basically, a galaxy S4 with no mobile phone chip in it) and using USB modems to use the cellular network when it suited me. The problem is, for a variety of weird reasons, a LOT of the realtime voice processing is also built into the baseband, along with the radio functions that we're all talking about here. So a lot of voice quality and noise cancellation and other things that you would really miss are built into the baseband and difficult to replicate on the main, more general purpose, CPU.
