Ever since I got this iPhone 4s turned back on it's showed a number 1 on the settings app I click on general and it say's software update. I click on that it say's, iOS 8.3. This release includes improved performance, bug fixes, and a redesigned Emoji keyboard. Underneath that it say's Learn More, I click on that, it gives a list of everything it's suppose to update. At the bottom there is the Apple support website. But also it says this update requires a wifi connection to download. I can't even turn my wifi on either.
