Is it possible to change back from ios6 to ios7?

I want to update my iPhone to iOS 7 but some people don't really like the 2 dimensional look. So just in case I was wondering if its possible to change from iOS 7 to iOS 6?

Yes, www.ios.com

If you upgrade to iOS 7 you will probably not be able to downgrade unless Apple is still signing iOS 6. There may be a short time after the release of iOS 7 where iOS 6 is still being signed, but that window is more than likely closed by now. If you have an A5+ device then there's no way to downgrade if you update. If it is A4 then you may be able to, but only if you saved SHSH blobs.

If you find a way to do it please tell me because I HATE this new look. Very unhappy!
