My Iphone 5S is working great - no issues what so ever with version 8.3 on it. For security reasons, if nothing else, I guess I should probably update to the latest version? I keep reading about negative aspects of the latest OS - like no more swipe to open, etc. and am wondering if those of you who have made the upgrade might share some tips to make the transition a little easier? Things that you've found that can make it easier to use in the new OS. I'm sure it will be a bit of a learning curve from my current version to 10! I will do the update with my phone connected to my laptop through I tunes - that's the best way to do it, right? This is the first Iphone I've had so am still somewhat of a "newbie" when it comes to updating. Appreciate any help you can offer me.
