update

i recently updated to 6.1 on iphone 4S........and now why is the picture not fitting?
and why do i have trouble using any button?
WHY GIVE YOU AN UPDATE THAT IS NO USE TO THE PHONE??
can i have my 4S back to normal? is there any one else with this PROBLEM

First:
Hard boot by holding sleep/wake and home until the screen goes blank and the apple symbol appears.

Second:
If that doesn't solve the issue do a restore in iTunes.

If it does work, you need to install 6.1.1

cheers 'mrplow' that was simple,now i am installing 6.1.1 and again thanks for your help.
