I have a iPhone 3G and a new iPhone 3Gs (2 weeks old), the 3Gs will show full signal, but then will go into searching mode and then report no signal. In the mean time my iPhone 3G is still on max signal.
I have searched the internet and see this is an issue around the world and appears not to be related to the provider, but the iPhone 3Gs handset.
So curious to see if anyone else has heard of this happening in NZ?
My current test is to turn off 3G and see if it can maintain a signal, but I have my doubts as it also drops the wireless from time to time, but not as often as the Vodfone signal. Turning the iPhone off or even doing a reset doesn't fix the issue. There seems to be no pattern to when or why it losses the signal or regains it's signal making it hard to monitor the problem.
