All of a sudden, Itunes won't recognize that I have even plugged my Iphone 4s in! The USB cable I'm using WILL be charging so I know the cord isn't damaged, there is power going to it. But Itunes won't pick it up, no matter how many times I shut it and re-open, unplug and plug in my phone. I just updated Itunes so I know I'm running on the most recent one, and I updated my Iphone as well a couple weeks back to the new iOS.
Also if I just plug my iPhone into my computer, a drive in my computer used to come up where I could copy/save my photos to my PC. Now, that drive never shows up anymore. WHAT is going on!?
Since this is a user forum if the ones have viewed so far don't have any recommendations they won't post. If you need immediate help you will be better off contacting Apple, VZW, or visiting the Apple Support site to see if one of the solutions for your issue helps you out.
In general, a good place to look is on the Apple support site by doing a search for your issue.
Was the Apple troubleshooting page able to get the device to be recognized by iTunes again? Please keep us posted so we can troubleshoot outside those options if needed.

They have this page for iPhones not recognized on Windows, but I don't know anything about Windows:
