A lot of Apple haters have been rubbing their tiny hands with glee recently after news reports of a security flaw in the iPhone OS 3.0 that could allow hackers to "Hijack every iPhone in the world" . Many were quick to point out how slow Apple were for not releasing a patch, and many simply made it a soap box for "iPhone sucks, use Android" rants. However, on July 31st, Apple released iPhone OS 3.0.1, with a patch for this SMS issue. It installs easily enough, job done. Of course, not being privy to such information as how to hack my own phone with this exploit, I can't check if it does the job. Either way, there it is. A fix. More detail on the OS 3.0.1 release notes .
