Some of you are all over the place with this issue.
1. Consumer Reports is a respected organization with as little bias as you can have (we are all human, I am sure there is some bias somewhere)
2. They recommended the original Iphone, the 3G, the 3Gs, and raved about the features in the 4, but stopped short of a recommendation because of their perceived antenna problems.
3. Obviously, not everyone has problems with reception, and for those that have no problem, this is a fantastic phone.
4. Obviously, some do have problems with reception, and for those that do, and love the phone and would like to keep it, they complain to and about Apple, in the hope that their issues can be fixed without the use of a bumper. Others just return it.
5. When Consumer Reports does not recommend a car model based on a below average reliability rating, this does not mean you shouldn't by the car. They have no power to stop you. It means they are giving you a heads up that there is a larger probability of problems. You may buy that model and experience no issues whatsoever.
My wife has a 3G and I have an Iphone 4. Holding both phones normally, standing next to each other, mine will go to searching for signal and hers will show 2 bars and complete a call. I still love the phone and will keep it, but there is a problem there for some people in some areas.
My previous phone was a Palm Treo and it never dropped a call from my house. The 4 does on occasion. It's just so good in so many other ways I am willing to put up with it.
