It’s time for anther QuickTip! Sometimes, I feel weird even writing about these because they are so familiar to me and I figure everybody already knows them! But, this is acutally a tip that Doug showed a man one time while we were waiting to get into a restaurant. So, I know some of you may not know about it!
QuickTip – There is a way to quickly put your iPhone or iPod Touch into “lock” mode without waiting for it to auto-lock on it’s own. To do so, just quickly press the power button (that is the button on the top of your device) one time. Do not hold the power button down (this would turn your device off) instead just give it a quick tap and voilà your iPhone or iPod Touch will lock.
In conjunction with that, you can also use your power button to bring your iPhone or iPod Touch out of sleep/lock mode. Just give it another quick tap and it will wake-up. It is basically the same as pressing your Home Button while your iPhone is in sleep/lock mode.
Doug acutally always uses this method to lock his iPhone…he turns off his auto-lock and just does it manually (as described above). I use this method a lot too but, I have to leave the auto-lock feature on because sometime I set down my iPhone and forget to lock it and my battery would totally be dead!

I have the auto lock turned off too. One thing I to find is that when I get a missed call my balance pops up and when I pull it out of my pocket it is still showing the balance and using my battery.
As obvious as this tip is, you are right, some people don’t know it. I kept getting calls from my sister in law, when her phone was in her bag. I never quite understood why. Then, one day, while having diner with her, I noticed she put her phone in her bag while still on. I asked her why she didn’t lock it. She said, “You can lock it?”
So … there you go.
My guess is that the call happens as she’s placing the phone in her bag, while still on and her hand is still holding it.
People that need tips like this are maybe not used to technology like we are. How is it common sense if you don’t need that button to wake it? If nobody tells you or you don’t read the manual – you won’t know. Everything seems doable with the home button.
I am glad for the tip. I smiled when I read what you wrote about reading the manual. I didn’t see a manual with my iPhone and I would have loved to read (a printed) one.

Its offtopic but can anybody plz tell me where in cydia is CallerID Fix for 2.2.1. HELP!!!
I was looking for an app to quickly lock my ipod touch and now I don’t need it, the power button tip does it for me. Thanks!
This thead is somewhat misnamed, although its actually Apple’s fault as they call it “Auto-Lock” in the settings screen when it is more like “Auto-Sleep” or “Button Protect”. You can configure locking and sleeping separately.
On my iPhone I have it set to go to sleep after 3 minutes of inactivity. I can also do that manually by pressing the top sleep button.
I also have my phone set to not require an unlock passcode within 5 minutes of the phone going to sleep. This means that I can leave my phone for up to eight minutes of inactivity before I have to enter the passcode. I still have to move the slider to “unlock” the interface.
However… Sometimes you do want to lock your phone so that it requires a passcode, even if the 3 minutes hasn’t elapsed. Any one know of a method to force it to do so, without having to disable the delay?
Thanks

Is there any way to prevent the phone from locking when put into sleep? I hate having to slide to unlock after waking..I want to be able to put the phone in sleep mode without it locking, Anyone know how to do this?
randy, go to settings/ general /passcode lock/ require passcode/ immediatly. and youre good
I think what Randy wants (and me too) is a “quick way to immediately lock my iPhone so that it requires a code to unlock” not as the default set up… but only to be used in rare occasions.
I like that I can go in and out of my phone for a while without entering the code. But once in a while you want to leave it on a table and know that it’s been immediately locked. And its a paid to adjust setting for this rare occasion.
Solution? Is there an app for that?
After much searching I found your post, I am looking for the same feature:
Any new info on this?
“… go in and out of my phone for a while without entering the code. But once in a while you want to leave it on a table and know that it’s been immediately locked [[Added: And passcode locked, not just swipe-locked]]. And its a pain to adjust setting for this rare occasion.”
I meant to say pain instead of paid.
Ttthats totally too hard
I do not know how to do this stup
