I just got back from "returning" my iPhone 4. I put it in quotes only because I still have to ship it in since I bought it on apple.com I went into the store and many reps attempted to convince me to keep it multiple times. I told them that thousands of people online were having the same issue and they claimed to have no heard anything. When I told them it was on NYTimes, CNN, Engadget, etc. they rushed to a macbook in the store to look. I was then told that they were told that a software fix would come out to fix the problem which is the bars just showing up wrong on the UI. I told them it was BS and showed them speed tests that proved it is more than just the bars on the screen. I then told them about Jobs response to "just hold it differently" and they were unaware of that as well, and immediately looked on apple's PR site. Now, I truly do believe that they were playing dumb in order to convince me that it was no big deal. Since I couldn't return in store, I had to go over to AT&T and have them switch my sim activation back to my 3GS. My iPhone 4 is now inactive and AT&T told me that when Apple receives it, my new 2 year contract will be killed with no fee. If it isn't, I just need to show AT&T proof of return. I have tried the exact same "death grip" on my 3GS that was killing my iPhone 4's signal, in the EXACT same location as my 4, and it does not kill any bars on my 3GS. There is no fix coming to the hardware itself according to the apple store.
