I can't reproduce the issue of touching the antenna to get the bars to drop. I can completely cover the bottom and cover the black band on the left side and nothing happens.
However, reception seems to be worse or fluctuate even if I'm not holding it sometimes. Behavior my 3G did not show. I had full signal at my parents house and work and now I can be sitting there and they go up and down very slowly at times. Other times it's a solid 5 bars. It never does completely lose the signal though.
I've also had problems with holding the phone causing signal loss so now I am using a 2G modded silicone case with no problems. Over the last four days however I have noticed my phone completely loosing a signal that doesn't come back until I reboot.
Anyone else having this problem? I'm new to the iPhone, is this common?
I am experiencing the very same thing....never had less than 5 bars in my town wherever I was now it fluctuates sometimes for no reason......very frustrating.....
