I had the same problem when I first setup my iPhone on Friday. It looked like it was connected, but it actually wasn't showing a valid IP address. First, check the settings on your iPhone (Go to Settings/Wifi/then click the arrow for your network to see that you are getting a real IP address--192.168...etc...).
The problem with my setup was that the password on my router was a hexadecimal password. I didn't realize this because when I connect with my mac, I don't have to specify that it is hexadecimal. I clicked the Forget this Network button, and then rejoined the network, this time choosing WEP Hexadecimal as the option.
Let me know if this works for you guys.

On occassion, I see the Wi-Fi Airport signal strength indicator on the the top left side, and its full strenght, but as soon as I begin to browse, the "E" appears and I am browsing on Edge.
I turned Airport mode on/off and also turning phone off.
It still doesn't work!!
