My iPhone 4 stopped working? - 1

I have an iPhone 4 and I was on instagram and listening ton Pandora when my instagram stopped working and I tried to click the home button multiple times with no success. So I clicked the power butoon to turn off my screen. When I tried to turn it back on it wouldn't. I tried many times to get it to turn back on but it wouldn't, and my Pandora was still playing. And when I tried plugging it in it still vibrated. But just please someone help I don't know why it isn't working!

Time for a new phone

  • Why iphone 3G games suddenly stopped working, the app open and closes instantly? Hi I noticed from last 2 weeks that my iphone 3G games which used to work perfectly fine suddenly stopped working. Whenever I try to open a game, it opens for a split second and closes immediately. I even tried rebooting my iphone several times but that didn't help. Please advise if you have any pointers.
  • Speakers on my Iphone 5 have stopped working? I don't think it is a problem with the phone itself because I can play music on my ipod on my phone without earbuds and the sound for siri works too with the speakers but its just sound on safari that isn't working, like I can't watch youtube without earbuds on. What can I do about this problem?

  • My iPhone charger stopped working I left my charger at my grandmother's house, so I borrowed my mom's charger for a while. Tonight I plugged it up to the wall and it was charging just fine. I plugged it up to my computer to sync something from iTunes and it was saying "USB device not recognized". Then I plugged it back to the wall and it still wouldn't charge. It hasn't been charging since then, and my phone is on 10%. What do I do?
