Apple Thoughts: Mossberg Sticks to His Original Review of the iPhone 4

"After 6 weeks of constant use with two iPhone 4 units, Mossberg found that in areas with 'average or strong AT&T coverage' the iPhone 4 generally performed better than the iPhone 3GS, but performed worse than the 3GS in areas with weak coverage. One iPhone 4 was a review unit provided by Apple, while the other was purchased by Mossberg."

I can speak from some limited personal experience here. I just got the iPhone 4 a week ago, and I've only made one call in that time in a weak coverage area. The call did drop. At home I have an AT&T Microcell, but I turned it off tonight and dropped down to 2 bars. I made 2 calls, and sure enough, they both dropped after a few minutes. All of that is entirely anecdotal of course, but it is interesting nonetheless. I do have to say that the Microcell has been a huge blessing. For the first time ever, on any carrier (and we've tried them all), I can make and receive cell phone calls at home.
