HEllo gurus.
I'm new iin all that stuff, and I'm just querrious about the way to back up my iphone for a case I run some "bad " application that will screw firmware definitions on device?
And how to restore it afterwards and make the device work as it was before the "dangerous" appication run??


thanks in advance.

Your post doesn't really make sense. You are using technical terms inconsistently and incorrectly.

The solution you are after is called iTunes. It has the ability to backup and restore your iPhone.
