Same thing happened to me. Wifi grayed out. I reset/restore the darn thing, and it worked. But a few moments later, same problem again. Did multiple reset/restores, but wifi never came back. So I think the wifi was shot. I Have a Linksys WRT300n v1.1 router...I wonder if the router blew out the wifi? Long story short, took back to apple and one of the geniuses replaced my wifi-less iPhone with a brand new one. I am still hesitant to turn on the wifi at this moment...afraid the same thing will happen again, and I don't think this time they will have a spare iPhone to swap with me. Anyone else encounter this problem???

I can't say i have a problem with the tech support though. The darn thing just came out last Friday.
In the end they said they could log a ticket and get back to me if they found out anymore information. I said no thanks, i'll just go back to the apple store and exchange it. They were really cool about it and gave me a new one which works just fine.
So back to when the problem started in the first place. The problem started after about a 2 hour ride in my jeans pocket on a hot day. Yea, it was toasty, but it should be able to handle that (my iPod has been through much worse). I don't know if the heat is what caused the problem, or i just had a lemon. In all my googling, I did find just one other person that had the problem so it could (hopefully) be a rare thing.
