how do I get rid of the ISO 8.3 update off my phone?
The ISO 8.3 has caused nothing but problems. Text messaging and calls are not working. I have to hard reboot my phone almost 4 times a day to get anything work. Phone was fine before I did this update and now nothing works.
How do I get rid of the 8.3 update?
iPhone 5s, iOS 8.3
