If your Wi-Fi doesn't automatically join or it disconnects after some time (most commonly seen after resetting network settings) try this. Credit to a poster in a forum for this 1. Turn on Wi-Fi and Ask to Join Networks 2. Press the Home Button 3. Launch Safari 4. Wait til the network list opens up 5. Press the network that you want to stay connected to Now the phone will automatically connect to it if you are within range and have wi-fi turned on. Not everyone has this problem so please no negative comments.
