Hi everyone,

Just a quick question...I was playing around on my iPhone this morning and noticed the auto-lock feature not working as I expected. So I tested the auto-lock feature in three scenarios.

1. iPhone not plugged into outlet/computer, listening (or not) to music, auto-lock works just fine
2. iPhone plugged into outlet/computer, not listening to music, auto-lock works just fine
3. iPhone plugged into outlet/computer, listening to music, auto-lock does not function, only screen dim functions.

I am running the new 3.0 OS.

Can someone clarify if auto-lock will function when iPhone is plugged into outlet/computer and I am listening to music? I thought my phone always locked under the 2.x OS...but maybe not?

Thanks for your help.

iPhone 3G, iPhone OS 3.0

    This was the case in v2.x as well - for example, when connected to power and playing music in my car (via headphone to aux input), the screen would dim but not lock.

    I just confirmed this by trying it.

    Windows 7, Iphone hooked to computer via USB for charging, itunes closed, auto-lock set to 1min, exchange activesync enabled, playing music listening via headphones.

    Results: Auto-lock will not initiate while in this environment.

    I unplugged and tried the same thing, auto-lock worked.

    I guess auto-lock does not initiate when plugged in via USB. My next test will be while plugged into a real power source (the wall socket).

    I see the same thing when using a vehicle charger - it doesn't lock when in iPod IF it's playing music (if paused or at a setlist menuu, it will lock). I think this feature was added somewhere around 2.0 (I considered it a feature as I didn't have to attempt to unlock while driving just to skip a song, etc).
