Why does my sound on my iphone 4s not work?

Why can't I follow people on Instagram?

It's been 15 hours since I could last follow someone. I use Instagram on my iPhone that I recently got for Christmas and I was just following a bunch of people in hope that they'd follow back(about 25) and it just stopped letting me follow. Every time I clicked follow it would go green for a second then go back to blue. I realised that on the computer I can follow people but its my iPhone that isn't letting me do so. Any suggestions?

I have uninstalled the app and restarted my phone but there has been no change.

Added (1). The annoying thing is that I can follow on computers and not on my Iphone:/ It can't be following the bunch that I followed as there were only 25 of them and it showed up in my list then I unfollowed them. It was after that when I could not follow anyone else

Should i call back again or wait?

I accidently called a friend ( Iphone 4) and I guess I pressed a button while the phone was in my hand doing downstairs while holding on to the handrail. Anyways, i guess he wanted to talk because he called back but I accidently hung up when my mom told me to go down for a second. I called back but he didn't answer. Should i try again or call later? I'm going to be busy anyways soon plus i didn't mean to call in the first place…

Has anyone paid to have their iphone unlocked the same day?

I have an old iphone 3gs that's in great shape. I'd like to unlock it from ATT so someone buying it can use it on TMobile. I put an unlock request in to ATT back on Dec 29 and it's still pending. Has anyone paid to have their phone unlocked online? I've seen a few sites that only charge around $5 to unlock. Are these legitimate? I don't have to unlock it - I know the IMEI is good to use currently with an at and t sim card, I just figured I could sell it quicker being unlocked.

How to transfer files from iPhoe to PC?

So I have an old iPod that I oly use to store my new music on, and my iPhone which has my old music on it and all my apps and stuff that I'd like to keep. Once I tried to sync my iPhone to my iTunes and it erased everything i had on it. I have everything backed up to iCloud just in case, but what I want to know is if there's a way to take the files from my iPhone and put them onto my computer so I can sync all the old content AND new content onto my phone so that nothing at all is lost? I'd really like to add old apps and music but I can't spend time and money downloading all the old stuff I had before back onto it ugh. If anyone knows a program that'd be great.
