Chosen Solution

I updated the iOS4.0 to iOS 4.0.1 the after 6 hours the screen of my iPhone is zoomed in and I can’t return it to normal view and I am having a hard time with the touchscreen.. help asap!

well, zooming is fun ;-) double tap the screen with three fingers simultaneously - that switches the zoom feature off then go to settings>general>accessibility and disable that feature

The double tap with 3 fingers trick worked. Not at first though. I was persistent and after several attempts voila! Thanks

still not working :'(
