Quick formatting iPhone? Deleting all data, but keeping the current iOS as brand new?

Besides going to settings-general-reset-Erase all content and settings? It takes hours long to format. I'm not asking for the restore with itunes. I want to format it quick. Any tools available in the software market?

Ok, so you don't want the option in settings… And you don't want to itune restore.

well… I got a hammer and a mallet… I also have an industrial electro magnent…

  • Will formatting an iPhone remove any police spyware? Recently got my iPhone back from the police and I'm paranoid they put something on my phone to spy on me, would formatting and updating from iOS 6 to iOS 7 get rid of ANY spyware or files on the phone?
  • What to do before formatting my computer? I'm going to format my PC. I have already have a backup of important files. I use this PC to sync with my iPhone. Now I don't want to lose all the applications and contacts which are present in the iTunes library(Songs don't matter). What do I do? Any other tips before I format my computer?
  • Restoring iphone, but keeping apps and contacts? It was getting a bit slow, and I want to restore it so its clean and fresh. My contacts are synced through icloud, so how will I get them back when the phone is restored? also, my apps will still be in itunes so I can resync them as well correct?
  • Is this fixable? And if it is can I use it while keeping my current contract? I have an iPhone 4th gen and I was wondering If I could switch to my brothers old iPhone 5s. I'm not sure if it's fixable though. The home button fell off and the screen is in horrible condition. A rough estimate of how much it would cost would be great too.
