Can't unlock my iphone by slide the bar and in the mean time
the monitor's like dead, can't play ipod either.

And I found out that if I knock it really hard, it will back to normal.
But could happen again right next time I try to unlock it.
Or if I sync with iTunes, it will back to normal.
And this could keep it normal for days, then happen again.

I thought it has something to do with the software.
But after I upgradedto OS3.0 and "did not" resotre it,it still happened.

I think it's a hardware problem.
Should I just send it back to repair?

iPhone 3G, iPhone OS 3.0

I get this too sometimes. Even when I go to slide to answer a phone call. It happened on my 1st gen. & now it has happened a few times on my 3GS...So far I haven't found a solution.

I have a similar problem happen fairly often. I can slide the box to the right side... but then it doesn't answer the call. I can hold the box at the right-most position for seconds but as soon as I let go, the box just slides back to the left and meanwhile the phone keeps on ringing.

It's incredibly frustrating. The worst user interface bug I think I've ever seen on a product - a phone that you cannot answer?..

My suspicion is that it mostly happens when I had previously locked the screen in the middle of using an app (rather than returning to the main screen and then locking it). If I then get a phone call, sometimes I cannot answer it. Apple engineers: please fix this.
