I am downloading iOS 5.0.1, which I hope will alleviate the low battery life issues that I have experienced since getting the iPhone 4S. I will report back after the update.
UPDATE: Install went flawlessly after downloading 800+ MB update. Let’s see if I can go more than a day and a half to two days before needing to charge.
UPDATE 2: Downloading the iPad iOS 5.0.1 update over iTunes. However, AppleInsider reports here that Apple is also pushing updates via its i-devices wirelessly. I wish that I had thought to check Settings > General > Software Update on my iPhone 4S before plugging into iTunes earlier!
UPDATE 3: It is interesting that the iTunes update is so large, when the AppleInsider images in the link above show the over-the-air update to be only 55 MB. I assume that iTunes grabs the full iOS system install while the over-the-air update contains only the files/changes needed for the update.
