Tired of swiping your finger to unlock the iPhone? Well then here comes QuickUnlock. This little app allows you to wakeup the iPhone from sleep by just clicking the Home button thrice (Triple Click). So instead of pressing the On button and then swiping your finger just tap the Home button 3 times.
Not only this, the app is different than normal unlock. If you do not launch any application for 10 seconds after unlocking the iPhone springboard, the iPhone will go back to the lock state!
Note: This is not a SIM Unlock. This is an App that lets you unlock the iPhone from sleep mode.
Cydia is an Installer alternative, that Installs on Jailbroken iPhone 2.x… Info here
