How to turn off the iPhone disabled feature on an iPhone 4?

My friends sometimes take my phone and continouslly typein the wrong password so my phone would be disabled. They would also threaten me for my password or else they will disable my phone. I know, I have great friends. I was wondering if I could turn of the disabling feature for the iPhone 4 and I have iOS 6.1.3.

You can't turn off that feature. The only way is to turn off the passcode, but I don't think that would be effective…
