TS1275 really hate new Maps App how can downgrade to iOS 5.1

I really hate the new Maps App.. how can I downgrade to iOS 5.1 ?

I live in Madrid, Spain, and the previous Google Maps App embeded with the previous operative system was SO MUCH BETTER than the new iOS,

in this map it never shows anything, I used to search for business names, or street address and in this new version you got with tom tom is an absollutely a mess. Have you tryed to search Madrid's main street "Paseo de la Castellana" the app shows "no item found".

New Apple Map is just disappointing! it is the WORST APPLICATION EVER. I used that App to orientate myself in the city.

I' dont want to jailbreak my devices, but there's got to be an alternative to downgrade to iOS 5 anywhere.

You just update to iOS 6 to start some app war with Google affecting Mac users worldwide in your private battle.

Please, HOW CAN I DOWNGRADE to iOS 5.1 ?? the best iOS built for mobile devices, and I remember the performance was better than the new one.
