About 4 day ago my itunes stopped working on my iphone?

A little more info would help.

  • Will Apple Retail Stores refill stock one day after launch day? If in any way an Apple Retail store runs out of stock after launch day of the new iPhone 6, is there any chance that by the next day there will be new stock already again? Or does sold out mean = sold out for a few weeks.
  • My old iPhone 5c won't turn on even though it was working fine a month ago and has just been in a drawer since. How can I get it working? I upgraded my iPhone a month ago and have been experiencing problems so I need to get it fixed. It will be weeks until I get it back so I decided I d use my old iPhone 5c until then. But I can't turn it on, it was working fine last time I used it a mo th ago. I tried charging for hours and hours and holding sleep and home buttons etc and it still won't come on. My charger is fine. How can I turn it on?
  • Keep getting the iTunes has stopped working message? Every time I plug my iPhone 5 into my computer I get the same message all the time "iTunes has stopped working) and it says "A problem caused the program to stop working correctly Windows will close the program and notify you if a solution is available." I have been getting this message for he last couple of months, I uninstalled and reinstalled iTunes and it has not helped.
  • IPhone 4s iMessage stopped working? Well, I was texting my friend. He owns an iPhone as well. Well, anyways we were texting when out of nowhere my messages send as regular texts instead of iMessages. I can still use iMessage with my mom so I don't know what's going on. This Is extremly frustrating.
