Where is my 4g/Wi-Fi icon on iphone 4s?

When I woke up this morning, I notice that the 4g/Wi-Fi icon is gone on my iphone 4s. I've tried turning my phone on and off, restarting the phone, and resetting network settings. None of that seemed to do a thing. Anyone know a fix for this or at least know why it may be doing this?

Should be on the top left corner

signal bars, carrier name, 4g(or LTE) or Wi-Fi icon

  • Why doesn't my iPhone 4S lock screen not have the slide up and use camera icon? The OS is 5.0.1 (duh) and I haven't jailbroken my iPhone. Is something wrong? Because I haven't had the camera icon on my lock screen since the day I bought my phone… I still have to double tap the home button like on ios5… Please help? I'm sorry for the extra "not" in the question…
  • Where is the camera icon for facebook cover on iphone? I used to be able to tap the camera on the bottom right of the cover pic in facebook to take a new pic in real time. Is this no longer an option? Is there another way to take a picture and have it go right onto the cover?
  • What is this iphone 4 status bar icon? This icon is a red horn with marks coming out of it simulating sound I suppose. I flip the silent/loud switch on and off and it doesn't make a difference. And a bonus, this icon is a phone, just a phone like one on a flip phone answer button. Please assist!
  • What is this icon on my iPhone? Basically I have an iPhone 4S and when I double click the home button the app history comes up. When I slide right the music player comes up, then if I slide right again my volume thing comes up. But next to the volume thing I have this little icon which looks like a triangle pointing upwards into a rectangle. When I click on it it says iPhone with a tick next to it and it says cancel at the bottom. Anyone know what it is?
