Why do I keep losing my sound everytime I take my iPhone off my iHome?

I unplugged my iPhone from my iHome and I keep losing my sound and then I always have to restart my iPhone in order to get it back and then I unplugged it again and I lost it again. If there's anything that I can do to fix this please let me know.

Make sure iOS us fully updated, and make sure that the iPhone is not connected to the iHome through wireless means (I.E. Bluetooth, AirPlay, or other means usually involving Wi-Fi).
If that doesn't work or you can't figure out how to do that, then turn on AirPlane mode and see if the problem persist.

I do this and the sound comes back for about 10 minutes, and then I lose it again.

  • Why is my iPhone 4 freezing up everytime I go to delete an app? Am I the only one having problems with deleting apps since the newest update? I've never had this problem before, and now everytime I go to delete an application, it just freezes and I have to reboot my phone by holding the home button and lock button.

  • Why does my laptop keep losing Wi-Fi connectivity? My laptop, a Dell Insprion, keeps losing Wi-Fi connectivity, and keeps showing the Wi-Fi connection as 'limited'. Wi-Fi on other devices like my iPhone works fine, while the laptop has problems. I looked at the power settings too, as it is sometimes set to switch off Wi-Fi to conserve power, but it does it even when plugged in. Also, it had no problems when I used it with the Wi-Fi in US for the past month. I'm in India now.
