Since we're on the topic, something similar to what happened to dinoalbert occured to me BEFORE I installed this app. I turned off my phone using the power button. When I turned the power back on, I noticed that it was taking a much longer time than usual to boot the phone. I tired of waiting and decided to switch it off again but by the time my phone booted, all my settings were gone and the phone was reset to its defaults.
Anyway, this hasn't happened ever since but I've yet to know what caused this. The only registry hacks I had installed at the time were SpeedyMenus, SpeedBoost and AnimatedMenus.
