Soooo… apparently Mac’s can’t catch viruses but the iPhone certainly can. There is a flaw in the iPhone’s software that allows any attacker to gain complete control over your phone. Flaw which Apple is aware of but still hasn’t patched. The details are simple and as such I will cut to the chase: if you receive an SMS with a single square in it, by the love of God – TURN OFF YOUR PHONE.
You have been warned, be safe, buy a Palm Pré.
