I am developing an application in which I use

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
}

-(void)handleSingleTap:(UITapGestureRecognizer *)recognizer {
}

Now my problem in iphone 3 after touch move it is calling handleSingleTap function and touchesEnded didn't get called. This happen only on some lower part of the screen when I move there touch end didn't get called.If I move long then touchesEnded get called.

But this thing is working properly in IPhone4 and IPad. In IPhone4 and IPad after touchsesMoved it is calling touchesEnded.

You're not the only one who has encountered this problem. I found a similar thread on Apple Support forum list : https://discussions.apple.com/thread/1507669?start=0&tstart=0

This thread dates from 2008 which coincides with the iPhone 3, so I guess there might be a chance this is an unfixed bug on iOS running on iPhone 3.

Otherwise if it's not the case, may be it's due to the fact that you are using a UIScrollView (whose controller is implementing the touch methods you listed above). By default, it has a method called : 

delaysContentTouches

That is set to YES. May be you should change it to no and say how it behaves.

If you are not using a UIScrollView, may be you are using two view and the second view containing the "dead area" is not connected to your controller ?
