The most current OS available for your iPhone is version 6.1.1, and is available for downloading.
Managing your updates is easier, now, than when the iPhone was first introduced. In the past, you had to update and sync to your computer. Now, when you turn on your iPhone, a window will appear, telling you that a new OS is available and ready to download.
To complete the update, just follow the prompts. It’s as easy as that. (You will need a WiFi connection to complete this update.)
Some users might decide to bypass this notification, and choose to update at a later time. This is fine, as long as you eventually update to the current OS. Choosing not to update at all can cause a host of issues later on.
Keeping your iPhone updated with the most recent operating software can help prevent glitches in apps you are running, and also help prevent your iPhone from crashing.
Friends of mine never update any of their devices or software, and as a result, their devices/software eventually malfunction. This can mean hours of downloading and updating missing/needed software to get their iPhones, applications, etc. working properly again.
To check which software you currently have:
1. tap Settings on your iPhone
2. tap General
3. tap – About – Scroll down to – Version; this should read 6.1.1; if your OS is 6.1 or below, it’s time to update
