Apple Thoughts: iPhone 2.2.1 Update Breaking Wi-Fi?

"This is news to me, and scary news at that, but it seems as though firmware update 2.2.1 has been causing some problems with Wi-Fi for many iPhone users. I've not had any problems, but then again, I use Wi-Fi only sparingly, and even when I do, it's never for an extended period. Also, I've updated to the 3.0 beta firmware, so I might have dodged a bullet there. If you have been having issues, and were hoping for a quick software fix, it looks like you may be out of luck."

I updated and this is the first I've read about it. I use the Wi-Fi connection at work and at home and haven't had one problem, neither have the other iPhone users in my family. So at least you know of 3 users that are good to go! All kidding aside, there are some posts in the Apple forum about the issue and some users have said they were told to bring the iPhone in for full replacement. Apple hasn't officially come out with anything on this however. The issue is affecting 2G and older 3G models, as well as some iPod Touch models. Speculation is that it is related to overheating with the Wi-Fi chip.
