iPhone: Change the auto-lock delay
Contributed by qmchenry 
Tagged: Apple iPhone The auto-lock feature of the iPhone causes it to “lock” the touchscreen and turn off the display after so long since your last interaction. The default delay is one minute which may be too short for you (especially if you are writing Tech-Recipes about the iPhone!). If you would like to change the auto-lock delay (or turn off auto-lock completely), follow these steps.
To change the auto-lock settings, tap the Settings icon in the home screen. Look for the General button in the main Settings screen and tap it.
In the General settings screen, tap on the Auto-Lock option which will cause a list of options to slide in. At release time, there are options for 1, 2, 3, 4, 5 minutes and Never.
If you choose never, you’ll need to press the sleep/wake button (the thin black button on the very top of the iPhone and to the right as you’re looking at it) to make your phone go to sleep.
Even with the auto-lock feature on, you can still press this button to lock your iPhone.

The touch screen tap is like the mouse click, so the app receives a mouse click on tap, when we say lock the touch screen it means not accept the event, it is good to keep the screen lock when not in use for durability..

I just upgraded to 3.0 and the option to make it never auto-lock isn’t there anymore! Just 1, 2, 3, 4, and 5 minutes? What’s the deal?

The “Never” option appeared the day I bought it and it disappeared. How do I get it back?
Annik said on July 7, 2009
There is no “Never” option in auto-lock; only 1-5 minutes…

The “Never” option going away has to do with your Exchange account. If the Exchange server admin sets it that way, the option will go away as a security feature.

My auto lock setting does not have the choice of never. Only 1-5 minutes. Is there a way around this? It locks up in 5 minutes. It changed after the 3.0 update. I have the 16 gb.

Can I change the passcode lock? It is only on immediately. There is not another option to choose? I have the 16gb. It also changed with the 3.0 update.

I discovered the same thing about exchange servers turning off the autolock “never” feature. I don’t know of a way around this that is great, but for me if I really want the phone on “never” for a while, I go to settings and turn off the mail and calendar for my exchange account. This is good if you only want the setting “never” to be active for a short time. If you want it to be permanently never, there does be a way to do it if you exchange account won’t allow it.
