Bell Canada issued a recall this last year for the power adaptors on their 2Wire Modems. Now, I had never had a problem with my modem's power adaptor. Didn't expect there ever to be a problem. Nonetheless, when they offered a new adaptor I took it, because common sense dictates me to do so.
Now I don't own an iPhone 4, yet. However, if I had a unit that was working fine I would have been one of those posting about it, because that I would feel it was my obligation to say "Hey, mine's working." I wouldn't be denying there is an issue (which there obviously is), I would simply be assisting in gauging the extent of the issue - that not all phones are affected. And even if my phone was functioning perfectly, I would exchange it if there was a recall ... because it's common sense.
I don't understand why you are being so bitter against those who have working phones. They were right to say there phone worked and to deny the issue was all encompassing (because I know first hand it wasn't) and they would still be right to exchange their phones if there was a recall.
Unlike yourself many people were unable to accept that there was a problem with the iPhone 4. People were very patronising when people were complaining about their experiences. I would like to know what those very same people would do if Apple addmiting that there was a problem, hence this topic.
