Would resetting an iPhone wipe out everything on my YouTube acct? I had to reset iPhone to factory settings. When I went to YouTube I was of course logged out but everything is erased when I logged in. All my favorites and my subscriptions and history. How can a reset affect what's in the account?
Why does my iPhone keep asking for updates? I've done the iOS6 update two different times and my phone just asked for it again yesterday. I don't understand. I have an iPhone4 btw.
Why does my iPhone keep asking for my Apple ID password? I have a 5c and I'm on IOS8. I went on it today and it just randomly asked for my password. I entered it but nothing happened/downloaded. I was just wondering if it was a glitch or something.
Why does iTunes keep asking me for a credit card? I made my iTunes account on my computer and for credit cards I put none. I don't have Internet anymore so I'm just using my iPhone. But I used my moms credit card to buy a couple apps. Then my cousin stole her credit card so she canceled it. So I tried to take it off but it won't let me even download free apps or anything it says that I have to fix my billing info, but I don't have a credit card please help!
