So I can delete some songs. But others won't let me delete them at all. I have an iPhone 4S by the way.

But some songs I can't even CLICK on! & those are the ones I can't delete. How can I get these songs off my phone completely? Or how can i just delete all the music off my phone & re-sync the music I want?

I put my iphone on silent, will it still buzz?

I lost my iphone at school today and I'm freaking out. I called it a couple of times and I had people text it for me so I'm curious on whether or not it'll buzz? Also if there's any way to locate it then please tell me! I haven't set it up on iCloud yet because I JUST got it recently and I use Windows mostly so it wasn't a big thing for me.

Also is there anyway for a caller to know that your phone is on airplane mode? I think I turned airplane mode off on my phone but I might have turned it on again since I was at school.

Why won't imessage/FaceTime work with ios7?

Everywhere I have looked it just tells me to reset network settings, but it doesn't work. Even after multiple attempts, resetting network settings does nothing. Reset the phone, still doesn't work

Last week I had to restore the phone for other reasons. Updated iTunes, completely restored to factory settings, downloaded everything back to the phone. Still doesn't work.

I have not found a solution online or anywhere besides "reset network settings" which does nothing. Is this happening to anyone else?

I have an iphone 5 if that matters.

Does iPhone lock code also protect the sim?

Probably a stupid question but I'm not very "tech savy"
Left my iphone at a friend of a friends and although it had a passcode on it, I'm worried that they'll be able to remove the sim and look through my stuff on their phone (… Long story… ) … Seeing as I had a passcode on the phone, would this protect my sim if they tried it in their phone?
And I can't just run around and get it because I'm 60 miles away just now urch.

I want to save my photos to a the Pictures folder in my user documents, but it only lets me import photos from my iPhone to iPhoto, and whenever I want to email a photo, it never lets me see the photos I have in the iPhoto library -- only the ones in the Picture documents folder.
