A few days ago Apple released iOS 5.0.1 beta build to developers which fixed some bugs and battery issues which are haunting some of the iPhone 4S users.
The public release for the update was slated for a later release.
Now Apple has started seeding the iOS 5.0.1 build to some of the end users for testing out the build, so some of the users who complained earlier about the battery drainage issue have received the update for testing courtesy the AppleSeed program.
9 to 5 Mac reports that those users receiving this update won’t be able to downgrade their devices to the earlier iOS builds but are allowed to update to the final build whenever Apple releases it within a few weeks of time.
A note for Users wanting to Jailbreak iOS 5:
Do not update to iOS 5.0.1 whenever it releases. According to member of the Chronic Dev Team, pod2g, the exploit that will allow Untethered Jailbreak on iOS 5 will most probably be not as easy if you update your device to iOS 5.0.1. So just to be on the safer side stay on the current iOS 5.0 until Chronic Dev Team releases their untethered jailbreak for iOS 5.
So if you’re not one of those unfortunate to face the battery drain issue, it makes sense to stay on iOS 5 for now and wait a while for the untethered jailbreak.
