I havent seen any issues with my iPhone. I have done extensive tests comparing to a motorola razr v9 which is an excellent reception phone.
I think people are typically making it up. Reception can always be better. AT&T network coverage is not that good. People love to nit pick apple products and this is no exception.
Unfortunately there will be no easy fix to appease people.
In my tests the iPhone does show fewer bars but gets reception at least as good as the v9. I do not have any more dropped calls on the iPhone than we do with the v9.
I guess it's possible that there are some problem units out there that may account for some of the complaints.
Maybe there's some particular scenario of network frequency or reception scenario such as multipath interferance which could be causing an issue in some cases where others do not experience issues.
I think reception of the phone is great. I wish safari didn't crash so often.
"I'm fine, therefore everyone else must be making stuff up". Right. Every one of the thousands of complaints on the Apple discussion forums and this one and in CNET, etc. is made up by someone who can't wait to bash Apple. Personally, I'd rather be able to praise them to the heavens and have a phone that works right.
