I think it’s worth reading and discussing: please don’t jailbreak your iPhone, a PCMag blogger wrote. According to blogger Larry Seltzer, there are serious security implications behind the jailbroken iPhone. [Apple has recently publicly saying that "jailbreaking" an iPhone is breaking the law and voiding the warranty.]

Once you jailbreak your iPhone is outside of all of Apple’s content and security controls. Miller says, for example, that the Cydia app installer runs as root on the iPhone. Apps that run on a jailbroken iPhone can run as root and do whatever they please, and are outside the iPhone app sandbox as well. This means that nothing prevents you from installing malware on a jailbroken iPhone and that malware could do all manner of evil things, probably including making phone calls.
Be in no doubt that such malware for the iPhone is possible and probably inevitable. 3rd party stores will have to have their own quality controls, but apps could be distributed other ways. For example, by spamming: “Click here on your iPhone for cool new free app!”. It works all the time on the PC, why not on the iPhone?
What do you think?

So it’s not that dangerous at all then really. About as dangerous, as the article points out, as having a Windows PC.
‘Dangerous’ would be perhaps something like base jumping.
