Apple has released iOS 7.0.2 for iPhone, iPad, and iPod touch. This is a bug fix release that focuses on rectifying an issue that could allow users to bypass the passcode unlock on the Lock screen. Another fix in this release is to re-add the Greek keyboard options for pass codes.
iOS 7.0.2 also brings iOS 7 parity across all supported devices. Alongside the launch of the new iPhones, Apple released iOS 7.0.1, but this release was exclusive to the iPhone 5s and iPhone 5c, and did not apply to the other supported iOS 7 devices.
Today’s update requires a WiFi connection to download and install, and the file size is approximately 19MB in size but this can vary based on which device you are updating.
To update go to Settings, General and then Software Update to get the update.
