WTF! Why did my iPhone deleted my music!

My step dad got me an iPhone 4 and at first i was downloading music from his computer but now that my computer is back on I tried it on mines. When I connected it, it sync and deleted all my music and one ringtone. And I can't drag any music back on.

How come I can't drag any music? I've been doing it the whole time.

You can't put music from two different computers onto 1 iphone. This is the one thing I don't like about iPhones, its the Apple Bullsh*t feature because they don't want people sharing music, they want each individual to buy music from itunes. I know, this has happened to me before but yeah just download music from your computer and ONLY use your computer for your iPhone so nothing gets deleted.

For some reason, Itunes only likes you to sync your device to one computer even if you log on to another computer. If you lost your purchased music, you can restore purchases, but if you lost music from a website or cd, you will have to put them all on again.

  • Why did the iPhone update add back a contact/contacts I had deleted? Pretty irritating to see a person show up in my contacts whom I deleted over 6 months ago. A name and face I don't want to see. I mean I deleted the pictures and everything yet I just found that his pic and all his contact info was in there. Is it just a glitch where it did a restore from 7 months ago for some odd reason!
  • Why did ios 7 put music on my iphone when i had deleted or removed these songs prior? So I had deleted or removed songs from my phone that i just didn't like anymore or got tired of. They were still on the computer and in the icould service but they didn't show up on the physical phone device itself. Now after ios 7 everything from the cloud is basically on my phone and i don't want them. Is there a way to reverse this or will i have to go through my entire library and hand delete the songs?
  • Why did Angry Birds get deleted? I've never tried downloading that game but I've recently heard it's been deleted… I meant flappy birds* omfg -.
  • The alarm goes off at times I haven't set on my iPhone5 (last year's). WTF? I work shifts and I set it every week on a different shift pattern. I previously thought I set it to go off at the wrong time but it has definitely gone off at a time I didn't set. The time it went off, that alarm was in the off position with no days assigned to it at the time. It wasn't the shift I had last week either (it didn't get it mixed up/carry it over from last week). What can I do?
