Apple has begun to push out iOS 7.0.2. The small but important update addresses a lockscreen vulernability flaw that could allow users to bypass the lockscreen. It also reintroduces a Greek keyboard option for passcode entry.
iOS 7.0.2 is available for the iPhone, iPad, and iPod touch. Weighing in at between 17 and 21Mb depending on your device, it requires a Wi-Fi connection to download.
