Hi. I have upgraded my iPad to iOS 7 and everything appears to be working okay. I have not done my phone yet and I probably will next week.
The interface looks a lot different and there are things that can make your life easier if you know about them; other things can make it difficult of course… just like anything new. Apple has prepared a very cool video that reviews the features and functions of the new operating system; I found a couple of other sites that explain the new operating system and some of its (hidden) power. I urge you to take a look at these so you can be comfortable when upgrading.
The upgrade on my iPad took about an hour so don’t try to jam your upgrade into a small amount of time. And leave yourself some post-upgrade time to look around and learn so you can be productive when you need to be with your ‘new’ device.
Here are three links to sites I liked:
