Well, I’ve had iOS 5 on my iPhone 4 for about 18 hours now. And in that 18 hours I’ve probably USED the phone a total of 2 hours or so (I was sleeping for 6 of those hours). Web browsing, text messaging, phone calling. And now I’m here to tell you about the experience.
Since I’ve only had a very limited time to use iOS 5, I will only be commenting on features that I’ve been able to properly evaluate as of writing this post. Also, I have not yet jailbroken iOS 5, so the following experiences are based on using the stock operating system.
