When it comes to data security SI and information stored on phones (smartphones and Tablets) provided, the safest is to use a word (cod) strong (to understand long and "tangled") consisting of figures. Most of the time users using passwords to restrict access to other people at personal phones, stop at simple passwords, generally formed from 4 numbers (The minimum number of CARAGE required for the password), to make sure they will remember them and can easily enter them when they want to use the phone. But this can be in some cases in the disadvantage of the users, considering that the same password type several times around the same people allows the respective people to guess the password access to the phone.
The solution for iPhone users who want to Improves the security of the phone, but I do not want to use a strong (or long) password for fear of not forgetting it, it is called CodeScrambler.

CodeScrambler It's a tweak for iOS available from Cydia Store (to have access to Cydia You have to have jailbreak made at device) that allows users to use short passwords (even made up of four characters) and easy to remember, and also increases the security of the phone mixing the keys from The virtual keyboard every time it is displayed. Thus the chances of a third person manages to guess the password become almost null.
CodeScrambler can be found and downloaded from Cydia at the price of 0.99$, a relatively quite low price if you count among those who put price on privacy and on data security stored in personal phones.
