Computer isn't recognizing my iPhone?

I bought a new iPhone 4S this morning. I charged it and it was fine. Then I went to connect it to my computer and nothing happened. I tried using another cord and still nothing happened. I charged my iPhone again and it charged. But it still would not connect to my computer or iTunes. I updates iTunes, restarted my computer, and restarted my iPhone. My iPhone battery life was like 50% but it wasn't low. So how can I get my computer and iTunes to recognize my iPhone?

Have you installed the drivers, when you plug it in it should automatically install them?

  • Why isn't my laptop not recognizing my iPhone 4S? This has been happening every time I try to plug my phone into my laptop. Does this happen to you, and what do you do? What should I do? Last time I plugged it in, it worked perfectly. Now it won't recognize it. What can I do about it?
  • Why isn't iTunes recognizing my iPhone? I have an iPhone 3g and iTunes 10.6.3. I want to upload music from my iTunes library to my phone, but when I plug my phone in, it doesn't show up on iTunes. It was working fine the day before yesterday, but now it's just driving me insane. Yes, i've tried unplugging it and reconnecting it, and closing iTunes and opening it again. Didn't work.
  • Why isn't iTunes (computer) recognizing my iPhone? I'm trying to load music from my computer onto my iPhone 6. When I try, iTunes won't recognize my device. It's not listed on the upper righthand corner. My phone asks if I trust the computer. I say yes. Then I get a message that itunes is getting an invalid response from my device. I never had this problem before.
  • Why is my Windows XP Not Recognizing My iPhone 4S in iTunes? I just got my iPhone 4S yesterday and I love it. But I can't seem to get music on it. I already have music in my iTunes library that I want to transfer to my iPhone but iTunes doesn't show the iPhone icon on the side. The computer recognizes it as a camera but not music. The computer is a windows XP. What do I do! D
