Iphone won't load onto itunes?

When i connect my iphone into itunes on my laptop the icon that usually appears when you plug a device in doesn't load so i can't sync any of my music or films etc and by the way i have used this laptop for my phone before its just suddenly started doing it.

Check the lead isn't broken see if it's properly plugged in see if it works on another computer

  • Why won't my music in itunes load when I log in? I'm using my sisters laptop and would like to put my itunes on it. I logged out of her account and signed into mine, but her music still shows up and mine doesn't. How can I fix this so I can sync my iPhone with my music without losing anything?
  • Why can't I load pictures onto my iphoto anymore? I have a mac by the way so last week i plugged my friend's iphone to my iphoto to transfer some pictures. I forgot to eject her phone and i just removed the chord from my computer and it says her device was still attached. Now I can't load pictures from my phone to my iphoto. My iphone doesn't show up on the list of devices connected on iphoto. What should I do? What should/can I do to connect my iphone to my iphoto so that I can load my pictures again?
  • My itunes won't load properly? On my iphone 4s when i click on itunes it loads for like a second then goes back to the home screen, i have re-synced it, turned it on and off and it still is messing up?
  • My iphone won't load iTunes or notes? So I click on notes/iTunes and it shows the iTunes background for about 2 seconds, then before it loads, it sends me back to the home screen. I have done a hard reset, and put it on charge until it was 100%, I have downloaded new apps, and my phone is not jail broken, and does not have any sketchy apps or weird Japanese apps - does anyone have any ideas for what I can do to load up these apps?
