Not being a comms guy, is this an indication that there is no one chip to cover all the various implementations and that adding multiple chips would have been too complicated? Hopefully the iPhone 5s, when it comes out, will address this, since as a user I shouldn't need to wrap my head around where my phone is 4G and where it isn't. Edit: Just read up on something called SDR. Is the logic for dealing with encoding and decoding hardware based or now in software?
