Richard Stallman told us that any piece of software that you cannot modify but someone else can has to be considered as malware. In this sense about any mobile phone must be considered as malicious, since there is (besides OsmocomBB, for which using is of dubious legality) no free baseband processor. Even more imporatant mobile phones are location tracking and bugging devices with built-in telephony functions. Thus it is no question why owning a mobile phone is a very bad idea in general (I know very few applications of mobile phones that justify these large flaws).
