I remember the same discussion a few years ago on symbian devices. Back then, it was possible on some SE phones to use the LEDs as a torch. Many people requested an torch-app for S60, but there was the rumor that long term illumination would kill the LEDs. Now, a few years later, there are at least two S60 applications to use the phones as a torch. And i don't know a single case where there were problems with the LEDs. So i think it's safe and i'm happy that a meamo N900 torch app is in development....

Thanks!
