Dear all,
what to do when your iPhone4 updated to iOS 4.2.1 doesn't work anymore?

I gently posed the iPhone on the table, as always.
The iPhone was on and locked and the battery far from being drained.
A few moments later, I took the phone to check a number and I discovered that the screen was not turning on, no matter which button I was pressing...
It's like it's been switched off, but it doesn't turn on if I press the power button...
If I plug the USB cable to charge it, nothing happens...
If I press any other button (even for a long time), nothing happens...

What happened? What can I do to switch it on?
Is the recent upgrade's fault? Am I the only one?

Thank you all in advance,
Stefano
 
You're not the only one with this problem, try this:

- started iTunes
- connected iPhone to laptop
- pressed Home button and On/Off button for about 10 seconds until I saw the Apple logo
- it rebooted and sync'd just fine with iTunes
 
Hi Stein,
thank you for your suggestions!

I had read similar thread, but nothing really helped...

I just figure out how to solve the problem: I pressed Power button and Home button together for something like 45 seconds... so don't give up after 10 seconds like I did before, keep on pressing...

I was happy to upgrade because of the alarm bug, but this new one is even worst!

By the way, does anyone noticed that fade transitions from a screen to another are no more fluid as they were used to be?

Have a nice day to everyone,
Ste
 
Thank you, thank you, thank you.

You just saved me a trip to San Antonio (the nearest city with an Apple store), to get my iPhone fixed.

Thank you again
Mondo
