A new jailbreak tweak called CodeScrambler is set to hit Cydia soon for iPhone and iPod touch, the work of developers “JQ-” and “Its_not_herpes.” CodeScrambler was created to rearrange the numbers on the iOS lock screen’s passcode keypad for extra security.
By rearranging the numbers, this jailbreak tweak can throw off people who watch you enter your passcode. So if someone has been watching you tap the bottom center portion of your keypad, and assumes you’ve entered the passcode “0000,” they’ve actually been tricked. The developer notes that there is a 1 in 10 chance of each number landing on the same square again.
CodeScrambler will be hitting the BigBoss repository in a few days, costing an honest 99 cents. The Glasklart HD theme is not included with the package.
