It seems that Apple has finally caught up with the rest of the mobile world. Apple tends to do things on their own time frame and OTA ( Over the air) updates are no exceptions. With iOS 5 Apple looks to change that. The feature has been in the settings since the first iOS 5 beta but it’s only active now in Beta 4.
The great news is that it works very well and very fast. I am concerned for the jailbreak community however. If Apple and the phone companies should desire to automatically push said updates. Apple could plug jailbreaks such as the popular Jailbreakme in a matter of hours rather than weeks.
