57 comments into this thread and not one mention of the string "baseband".<p>Surprising, as that is far and away the most interesting thing that could happen in this space, and it continues to not happen.<p>Depending on the phone and the implementation of the baseband firmware, your carrier could have as deep as <i>DMA access</i> to that computer in your hand.<p>Osmocom is interesting, but it is 2G only, works (almost) exclusively on euro-GSM handsets, and is barely making calls at this point.<p>This (the op) is all very interesting, but all that matters is getting an open baseband firmware that you can protect from the carrier.
