on my 3G also! Not cool, especially when you have no idea it's happening until you try to make a call or text someone and it keeps failing to connect even though you have full signal strength.
Anyone else experience this problem?
CNet. How about a survey of iPhone users that experience the dreaded "Zombie" mode. You know, the one where your iPhone looks operational, yet can't receive or send calls or texts. This is a frustrating problem for such an expensive "phone". Maybe Cnet can get to the bottom of this since Apple and AT&T won't acknowledge there is a problem.
The forums on Apple and AT&T are full of people with this problem on the iPhone with the 3.1 update.
Knowing that they are working on a solution might keep me from taking the phone back and trading for something that works.
