Sometimes our iOS devices fill up with junk we don’t need: old cache data from Facebook conversations, text messages that are years old, etc. PhoneClean can help you take care of that.
Just run over to iMobie (Link) to download PhoneClean, and install the application on your computer. From there, connect your iOS device and launch the app. It will search for all those unnecessary files and ask you if you want to delete them. If you okay it, PhoneClean will delete those files and clear up some space on your iPhone or iPad.
It’s actually pretty cool, and it’s free. It doesn’t require a jailbroken device or anything special.
