It seems the development team of an Israeli-based company called Cellogic spent the last 8 months toiling on the development of an Android-based version of FlyScreen. The app that was until recently available to owners of Symbian S60 devices can now replace the lock screen of your Android running handset as well, visualizing a new screen that hosts widgets allowing access to Twitter, Facebook, RSS, Weather forecasting sources and what have you. The program runs flawlessly on HTC cell phones equipped with Android 1.5, but it seems the app needs some finishing touches, because the particular way it runs on the Samsung Galaxy I7500 leaves a lot to be desired.
The whole idea is really nice, but it´s nothing to do with what the phone screen locking function is all about, which is, erm, screen locking. The whole point to it is saving energy and hence, extending battery life, preventing the possibility of your phone erraneously dialing numbers all by itself while in your pocket etc.. FlyScreen goes against this by making your display light up during information updates, which will certainly shorten the battery life of any handset.
