You can now add two new applications for your iPhone 4 . Use the iPhone 4 LED Flash to lighten up in the dark and access iPhone 4 camera quickly from your lock screen without going to home screen.
FlashCam jailbreak app allows you to do both these. The app available for Free in Cydia is pretty clean and we found it very handy . After installing it on your iPhone 4 , you can access the settings from your Settings menu under the tab FlashCam. It can also be used with Passcode enabled devices . You can launch the default camera application or choose from other app store apps like Instagram, Camera Plus .
Simply launch Cydia and type FlashCam in the search box. Hit search and wait for the results to appear . Tap to install. Restart springboard and go to Settings to enable it . After being enabled , click the Power button on the top to bring the Lock Screen . The two buttons “Flash Light” and “Take Photo” appears only on the lock screen and charging screen when connected to the USB .
You may have to disable any lockscreen theme and turn on off the FlashCam several times via Settings menu to enable it for first use .
