99% of all Android Devices face Security Threat
A patch has been released by Google to solve this issue; however it only works for Android 2.3.4 and Android 3.0. So this means that all devices with Android 2.3.3 and below are under authentication threats.
More research concluded that syncing contacts and calendar data is done insecurely prior to v2.3.3. Even the Gallery app uses the insecure method even in the latest smart phone version of Android.
