Internet problems (iPhone 4)?

My Internet in my iphone works fine in chrome and safari, but when I use another app (like YouTube) my Internet won't work, I have tried rebooting my phone, please help.

Try restarting it from your settings…

Settings > General > Reset > Reset Network Settings.

Restart

Try to uninstall the youtube apps then reinstall it again to your phone. Hoping it can help you.

What does a circle in place of 3G on IPhone 4 mean? It keeps changing back & forth

  • Why does my iPhone still charge for Internet even when I'm not using Internet? So, I recently got a pay monthly plan with my new iPhone 4s. When i'm out and about I'm usually updating my twitter and Facebook account. But, when I'm put my phone down, 3G still says I'm using it and charging me. So do I have to turn it off when i'm finished? Or is there a much easier way?
  • My Iphone is not letting me access the internet or internet based apps? I have an Iphone 5. Never had any issues but now it won't connect to the internet or any apps. It does the same thing it does when I have no service (just has that little circle symbol that means it's trying to get through). Orginally, I thought it must be a universal problem but everyone else has service and they are in the same location as me. Also I always use my phone here with no problems. I have tried turning it off and on again but nothing.
  • Is talk talk having problems with its Internet connection? I'm with talk talk and my Internet has been off since this morning. I've unplugged the router and plugged it back in, but that made no difference. I'm using my iPhone which uses 3G
  • IPhone 5 internet connection problems? My iPhone 5 won't load anything that needs a internet connection. It's says my Wi-Fi is connected but it doesn't load anything so I thought it was my Wi-Fi then I tried using my cellular data and that won't load anything either. (I still have data left on both, I'm not over my limit) Anyone know how to fix this? Would turning my phone off then on again fix it, I would've already but the lock button sticks n doesn't work properly.
