I've been searching around the internet for a network card that could allow me to transmit internet from my PC to my iphone.
I already have internet on my PC through a normal network card (with wire), i just need to transmit it further to the iphone.

My Iphone 4s ringer is not working

The ringer is not working, no alert, no message alerts, no typing clicking sound, not even the music works! It's not the silent button on the upper left part of my phone above the volume. I tried rebooting several times now and it worked for a split second then it stopped working. I tried backing up all my things back to the phone and still not working. I even tried the hard reset or whatever that is and still nothing! Funny thing though, is that when i plug my earphones I hear the music and the clicking sound when I type something but when I unplug the earphone (headphones) it doesn't make a sound again. Also I noticed when I unplug my earphones while listening to music the volume option at the bottom disappears… I'm not sure why… But this is driving me CRAZY!
