New day, new … well soon to be new app in Cydia: SpringFlash. Since the jailbreak is due very soon, BigBoss developed SpringFlash, the first iPhone 4 only Cydia app. SpringFlash is a springboard activator based LED flashlight for your iPhone 4. In short, you can have a touch of a button for a bright LED flashlight without hassling with unlocking your iPhone, closing your app, or even turning on your screen.
To use this you will have to: jailbreak ( when the jailbreak will be released ) , install the app, go to settings app, activator pane, pick the activation method of your choice, and select the Flashlight.
Like all apps BigBoss writes, you will find SpringFlash for free in Cydia.
