Restore my Iphone to get rid of IOS 6?

I hate IOS 6. I just want my old google map app and my old you tube app back. If I restore/reset my Iphone 4 will I lose the IOS 6 update and get back my old apps?

You can't, but if you really can't stand it than you can sell yours and buy a used one off of eBay that is still running iOS 5, also if you want the map just go to google maps website and click the little bookmark button at the bottom.

YouTube is available from iTunes

maps.google.com or download the Google Earth app
