ITunes won't detect iPhone 4?

My iPhone 4's battery went dead for the first time in like a year. Then I connect it to the charger, after that it said to connect to iTunes for it to start. The problem is that when I plugged it in the PC it didn't detect it. I thought maybe the computer needs to restart, I did but it still didn't detect my phone. I then when to my dad's PC and borrowed my sister's laptop and it still didn't detection either of their iTunes.
Why won't it detect?

Also my phone is still dead, it won't charge.

The phone is dead

I would say plug it in the charger and even though it says connect to iTunes leave it plugged in. It should still charge.

Leave it plugged in for an hour.

Then plug it into iTunes. If it still doesn't recognize then your phone may be in recovery mode which unfortunately your phone may have reset and lost all its data.

You may need to google How to get iphone into recovery mode to figure out how to get your phone started again.

Granted this is a worse case scenario and if you don't want to go through this recovery stuff on your own you can call apple support at 1-800-MYAPPLE and ask them what to do. They are closed now so you can call them tomorrow

  • Why won't any computer detect my iphone 5? Hi! I have an iphone 5 and i've always had my phone unlocked until now. My brother put a pin on the phone as a prank and now we don't remember what it is. I can unlock it if i connect it to itunes but no computer detects the phone. I tried different cables and multiple computers. What's weird is that if the iphone is off and i connect it to a pc it turns on. What can i do?
  • Why won't my iTunes won't detect my iPad 2 or iPhone 4S? My iTunes version is 10.6 and it won't detect my iPad 2 or iPhone 4S in the devices tab. My computer recognizes it as an iPad and an iPhone but it won't show up in iTunes. I have uninstalled everything related to iTunes and Apple and re-installed iTunes and that did not help at all. I need some help. Thanks! I forgot to add. I'm running Windows 7 64-bit Lilpuppy: i updated to iTunes 10.7 and it still will not recognize my devices
  • My iPhone won't detect home Wi-Fi? My iphone only detects my home Wi-Fi when its right next to the router! If i move 5m away or into another room, BAM. Goes back to 3G. This is really annoying. I have tried to forget the network and reset all network settings. They don't solve the problem. Any suggestions or information would help greatly.
  • My iphone won't detect Wi-Fi anymore? All of a sudden my iphone won't pick up Wi-Fi! I dropped it, and it seems that around that time it stopped working, is that the answer? I've tried to reset network settings, turning on airplane mode, etc. But nothing will work. I really don't want to restore it, that is a huge pain. So any suggestions on how I can fix this preferably without restoring? @Bethany, i've tried that too )
