Duplicate iPhone apps
I have an iPhone and quite a number of apps = I was reviewing the iOS apps in the Mobile Apps folder and there are some of the [I assume] older apps in the Mobile Apps folder along with the newer versions = see --
Can I safely delete the older apps and keep only the newer one -- in the shot above my understanding is 3.7.2 is the app and the .1 and .2 means those are dupes = but if you look the sizes are different so they are not really pure dupes.
In other cases, I have an app = Air Sharing 3.1.ipa and then there is a newer one Air Sharing 3.4.3 - can I safely delete the older one?
iPhone 5s, Other OS, iOS7
