An example of the sort of thing that gives me doubts. They refer to another supposed demonstrated attack called "Wifigate", which no-one has been talking about, except for themselves. And when you read the details, they claim that iPhones come preloaded with a bunch of WiFi SSIDS that the phone will automatically connect to. mostly telecommunications companies. Up until recently I used to work for one of those listed companies, and I have owned iPhones continuously since the iPhone 3G. I can tell you categorically that iPhones do not automatically connect to SFR wifi hotspots like this company claims. This fact destroys an important part of their claim for this current "attack", that you can be affected even if you've never connected to a Wifi hotspot.
So that's one guaranteed example of exaggeration right there, which seeing as it's the only piece of information in the article that I'm capable of verifying myself, makes me very distrustful of the entire article.
