Apple just pushed out iOS 9.0.2 for all devices. This is a small update in my opinion. It just fixes. 

Fixes an issue with the setting to toggle cellular data usage

Resolved an issue that prevented iMessage activation for some users

Resolves an issue where an iCloud Backup could be interrupted after starting a manual backup

Fixes an issue where the screen could incorrectly rotate when receiving notifications

Improves the stability of podcasts

What does this mean for a iOS 9 jailbreak? It will most likely be pushed back in fear of another iOS update.
