Is there an app (normal, jailbreak) that will keep my iPhone (3GS, OS 4.x) screen on, indefinitely, when it is plugged in, regardless of what app is running in the foreground?

The Gentle Alarm keeps the screen active when it is plugged in, but I guess that is a feature that each app has to implement, not something that you install to keep the screen active for all apps.

I use Kensington's Nightstand every night. Sure beats having a separate alarm clock by the bed. And no, you don't actually have to use (or even own) their charger.

First, I just tried on my iphone and even calculator stays active after 1 minute, even if the screen dims out. So maybe your question is really just about keeping the screen on.

Anyway, I can think of two solutions: kirikae with backgrounder might do the trick as a side effect. If not, you can use SBSettings with Autolock toggle to do it manually and temporarily set the auto-lock to never. All of them you should find in Cydia.

edit: as none of the above actually worked, here's some update.

Some custom toggles on SBSettings seem to just not work indeed. It's probably due to getting outdated or conflicting with something else, two common problems we find on cydia apps. BigBoss is kind of similar to SBSettings and also have an Autolock toggle. You could use it along with some multitasking, leave it on the background and use it as needed. It hardly have any conflicting issue.

Unfortunately I can't find many more ideas to this.

Only thing I can assure you is that I just tried SBSettings's Autolock toggle on my iOS 3.1.3 and it works. It also says it's updated to 4, so most likely it's either problem with 4.1 or conflicting with something else you've got installed. And believe me, there are conflicts from the least expected things (look at the comments).

Yes I meant "screen on". I just realized that the OS allows "never" as an autolock option without jailbreak, but the SBSettings will make it easy to just do this when I want, not all the time. I think I'll delete the question, as it is just part of the OS... –  user588 Dec 24 '10 at 16:45
    
@mankoff don't you dare to ever delete relevant questions just because after they're answered they look like it was "obvious"! ;) –  Cawas Jan 4 '11 at 17:25
    
OK. As you can see I haven't :). I think it didn't let me? Anyway, AutoLock Toggle (SBSettings) sounded great but doesn't seem to work. Still looking for a solution... –  user588 Jan 4 '11 at 17:29
    
@mankoff that's sad news. :( I'll update the answer and try to help. :( –  Cawas Jan 4 '11 at 18:13
