I noticed that I was constantly having issues with the Wi-Fi connecting. I ran across this fix in another website. It worked like a charm. My Wi=Fi connections are screaming now!

"What you need to do is set the hex-key not the password for your wifi. To do this, go to -->Settings-->Wi-Fi-->touch the blue arrow key of network your connected to-->this will bring you to the settings of your network-->tap "forget this network" (this will allow you to be promted for the password/hex-key again)-->confirm "forget..."-->go back to Wi-Fi networks-->tap your wi-fi network you wish to connect to-->in the security box, tap the blue arrow (this will bring you to the setting for WEP password or WEP hex or ASCII)-->touch WEP hex or ASCII-->tap back to password-->finally tap in your WEP passkey."

"You can confirm that you are really connected via wi-fi because the iPhone will report a router and a DNS number. if it does not, You are not really connected to wi-fi, even though the iPhone wi-fi symbol will be showing at the top."

Please post your results!
