From the article "It is currently unclear how isolated the baseband processor is from the rest of the system's hardware."
Is this a problem? I was under the impression that the baseband controller was regarded as one of the more likely areas to insert "extra functionality", but I'm only going on info from security conference presentations.
EDIT: First Item in the TODO section: "Reverse engineer details relating to the Qualcomm MSM8610 baseband processor." Good to know they're on it.
