A friend stopped me the other day to ask about a situation with his iPhone 5.
The phone keeps bugging him to upgrade to the latest version of the operating system, which he really doesn't want to do.
The phone asks him twice a day if he's ready to upgrade.
The dialogue box has two choices -- yes, upgrade now, or no, remind me later.
To compound the issue, his phone is full, and he's afraid initiating the upgrade will mess things up.
He understands the consequences of not upgrading, and he just wants the nagging dialogue boxes to stop.
It didn't take too much searching to find a thread or two on the iPhone discussions at support.apple.com to find someone in the same boat.
I wish I could take the credit for coming up with the solution, but I'm just really good at internet research.
It turns out Apple downloads the update to your phone and then asks if you'd like to apply it.
To get rid of the nagging dialogues, you need to find and delete the update.
In your iPhone's settings, click on General, then click on Storage and iCloud usage.
Depending on your version of iOS, it may just say Storage.
Look for Manage Storage and touch it to show a list of all your apps and how much space each is taking up on your phone.
Look through the list for the iOS update. Touch the update on the list and click the Delete button on the next page.
This should stop the constant request to install the update.
You might also want to go into the settings for iTunes and App Stores and uncheck the choice to automatically download app updates.
You'll just have to remember periodically to manually check for updates that you do want to install, but you can do that from the App Store directly on the phone.
