Wondering if your iPhone software is up-to-date? It is very easy to check and perform an update if necessary.
Go to Settings> General> Software Update It will tell you your current version and prompt you to update if you do not have the latest iOS. Always a good idea to plug in to your charger while doing updates if you can. As of today, the latest iOS is 8.1.3. Although it was only a minor update, it is a good one to install. 8.1.3 fixes a number of small bugs, but does not fix the “GMT bug,” which causes calendar syncing issues and time zone confusion for some iOS users. It does help reduce the amount of storage required to perform an update, which is a very good thing.
