How can i undo the latest ios7 software update for my iphone4? It completely screwed up my phone!

Question

I updated my iPhone 4 a few days ago to the latest operating system, iOS7. I've always proceed with the operating system updates because I assumed there were security fixes included as well as other fixes that were supposed to make the system run better. I haven't had any significant problems with updates in the past, except for some minor differences in appearance that didn't bother me.  This time but the update appears to have completely screwed up my phone.
My first complaint is, where the **** did all of my apps go?? I paid for them, and now they're gone. Are they hiding in the iCloud? I had over 3 screens of apps, and now I've only got 1 screen.
My second complaint is, what was wrong with the appearance of the interface and icons in the previous version? The new system has gone with opaque pastel-colered icons that, frankly, I don't like as much as the icons in the previous system.  And why does there have to be a gray band on the bottom row of icons?
My third complaint is everthing else on the phone is screwed up. Nothing works like it did before. Most of the photos I had on my phone have disappeared (iCloud??) Granted, my complaints about the appearance may seem trivial, but this is really annoying.
Can I reverse the iOS7 "downgrade" and go back to the good old days with the previous version when everything worked just fine and I was able to access all of my apps?
