Do you have trouble with your iPhone, where it goes dark and it doesn’t come on no matter which buttons you press… then all of a sudden it comes on?
What causes this?

The iPhone is on but no matter what you do it doesn’t come back for at least 10 seconds when all of a sudden the screen reappears.

Today, while receiving a call my screen locked up, it didn’t matter what I pressed on the screen. It was really locked up. This has happened before but not this had, where I basically had to power reset the iPhone 3GS.  This is with iOS 4.01.

Not really pleased with Apple and AT&T and their lack of response to these issues.

We have heard that AT&T is rolling out new towers, but nothing is changing in my area, other than continued troubles with dropped calls, actually getting worse.
