I noticed today while at a friends house who has a first generation iPhone that he had FULL signal strength while I had NONE on 3G. As a matter of fact, I couldn't even place a call. My point is, isnt the phone supposed to dynamically switch between 3G and Edge? I had to manually turn 3G off and once I did, I got full strength signal in Edge. Suffice to say, this is quite annoying... Now, I guess my question is this; is this a hardware thing, a software issue, an ATT issue or an Apple issue? One last thing of note, sometimes where the 3G/Edge icon is I see just a dot. I have no idea what significance this dot has anyone know? TIA.
