I do not consider myself to be an Apple Fanboy, as many seem to call people who like Apple, but I will tell you this. I will give you my unbiased thoughts as someone who runs both PCs and Macs, which I love both, and I will never permanently choose one over the other. Windows 7 rocks!
I do own an new iPhone 4, and at this point in time, I have been dropped from one call. Unfortunately, phone signals so not like to travel through large hills that surround narrow roads. I have tried to force dropped calls by holding the phone in the ways that people are complaining about, and I stay connected to the call. I do see a fluctuation of two or three bars, but I do stay connected with good call quality. I did purchase a Apple's overpriced bumper and repeat the same tests. With the bumper on, I do not lose any bars. I agree with many other people when they say they should not have to buy a case to help signal. I look at it as lagniappe. I have to say though, Apple's bumper is not like the cheap rubber bands that you find at all the kiosks in the mall. It was definitely over-priced, but I am glad I went with it. Apple's bumper is a mix of rubber and hard plastic with metal covers for the buttons. One thing that everyone can agree on with Apple is that there products do look great. They did put quality into their bumper, so I was pleased with the results.
Anyway, I am receiving better call quality with the iPhone 4 than I was with my older iPhone 3G. Am I just lucky? If I am, then great. I do not regret getting the iPhone, and I have to say that it is by far the fastest and most feature-rich phone I have ever used. I am not one to knock something before I try it, so I like to sit back and read what other people are saying, but allow myself to draw my own conclusions. As I have mentioned. I am happy with my iPhone. If you are not getting the results you anticipated with your iPhone, just return it and choose something different. How did this turn into a lawsuit in less than a month? Why did something like this turn into a lawsuit? From the sounds of it, many of the people commenting here do not own iPhones, so it is hard for me to take your comments into consideration when making my purchase decisions. I have to say, I am glad I did not listen to many of the comments found on here. I love my iPhone so far.
I hope this helps.
