Soon after launching iPhone, I remember Steve explaining why Apple did not put Flash or Java support into the wonder device. If I'm not mistaken, stability and security were the factors why the Cupertino company said no to these extremely widespread technologies.
iPhone is a really cool device but how secure is it? It turns out that iPhone is a huge security risk. FastCompany has made an experiment in collaboration with a security expert Rik Farrow and unfortunately Mr. Farrow was able to do "amazing" (to be short, the attacker can take a full control on the device by accessing messages, emails, even conversations and much more) things with the wonder device. If you are "lucky" owner of iPhone you may wish to at least turn off your WLAN functionality and watch this video.
