I have owned each iPhone, usually within a few days of release. Yes, since the iPhone has always supported bother a cell connection and a wifi connection, the devices have both. Additionally, people have been reporting problems with both the 3G antenna issue and connecting to wifi routers. I had both. I said nothing about them both being related to the same antenna problem. I suffered from both. I exchanged my phone today at the Apple store in downtown SF and have had no problems since. Don't understand why I was downvoted SO much for that. I'm happy that you downvoters have had excellent experiences with the new device. Did you wait in line for over 5 hours for yours? If I wait that long for a product, I apologize for having the expectation THAT IT WORKS.

Could you explain why? I don't own one and never really read much about Iphones.
