Just so you know when I forgot the password to my password to my iPhone remembered that I choose 1 from the top section 2 repeated numbers from the row below 1 below that and then a zero. So I tried it untill it said "iPhone disabled connect to iTunes", this is when I found out you can reset the disabled time by clicking on a computer the backup button. So therefor you could successfully create a program that tries passcodes 5 or 10 times then tries and fails to back the iPhone up. (There is no need for a backdoor or anything fancy)
