Ah, it's not just me that wants to also use my smartphone as a torch. Ever since the N93, I've wondered why this isn't a built-in feature. All In One Torch is a Python hosted script that offers pulsing of the camera LED in the likes of the N95 and E90, along with always-on white main screen. The only downside is that you have to go through a silly Rapidshare system to actually get the download. Shout here if you can't grab it. The usual warnings about knackering your LED hardware apply, of course. And familiarity with running a Python script will help (via Symbian blog)
