Apple on Wednesday (30 September) released yet another software patch iOS 9.0.2 to all its iDevices via OTA (Over-The-Air), just a week after the roll-out of the iOS 9.0.1.

The previous update had fixed some glitches in Safari browser, Photo apps and custom APN setup, but failed to plug the major security loophole in lock screen bypass code system, which can be tricked with simple five-step procedure to get access to user's photo and contact list.

Thankfully, Apple has just confirmed that the new iOS 9.0.2 rolling out to the devices comes with software patch in tow, thus tying all the loose ends before the next major update v9.1, which is set to be released in November.

Besides the Lockscreen bypass bug, the new iOS 9.0.2 is also said to fix another major glitch related to cellular data settings options, wherein some select apps were cut-off from accessing mobile data connection for update.

Here's change-log of Apple iOS 9.0.2 update:

  1. Fixes an issue with the setting to turn on or off app cellular data usage
  2. Resolves an issue that prevented iMessage activation for some users
  3. Resolves an issue where an iCloud backup could be interrupted after starting a manual backup
  4. Fixes an issue where the screen could incorrectly rotate when receiving notifications
  5. Improves the stability of Podcasts

However, there is no word from Apple on if the new iOS 9.0.2 enables the App slicing feature, which was first promised in iOS 9.0 but didn't materialise even in the last iOS 9.0.1 update. Stay tuned for more updates.
