I received my iPhone4 this afternoon and I'm surprised how poor the wifi reception is. As I'm typing this, my iPhone is on my desk, four feet away from my wireless router (Airport Extreme), and there is only one sheet of plywood in between the two. Despite being so close, the iPhone's wifi reception indicator shows 2 bars out of 3. The router is on the third story of our house. If I go down one floor, then I lose one more bar. If I go to the first floor, I lose my wifi connection. There's no "death grip" here. The phone is laying flat on a desk/table. On the other hand, with my iphone 3GS (and my macbook) I get 3 bars out of 3 everywhere in the house. Anyone got wifi reception as bad as me with their iPhone4?
