More FAQ suggestions

ese problems include the inability to connect to Wi-Fi, 3G and/or Edge, lack of push notifications and issues with the YouTube application. Fortunately there are several fixes you can try to correct these data issues on your iPhone:

1. Reset network settings. Touch Settings -> General -> Reset -> Reset Network Settings.

2. Still having problems? Touch Settings -> General -> Reset -> Reset All Settings. Warning: You will loose all of your preferences.

3. For YouTube problems on jailbroken iPhones try installing youtubeFix from Cydia or another package installer.

4. Restore your iPhone as a new phone. This is a slow and tedious process but will reset your iPhone as if it was new from the factory. Although this should fix all of the above issues, you will have to reload your contacts and media onto the iPhone from the computer manually. To restore:

- Connect your iPhone to the computer.

- Run iTunes.

- Under the Summary tab select Restore.

- Select backup if you wish. When restoring as a new iPhone you will not use the backup.

- When the process is complete the iPhone will restart.

- When the Set Up You iPhone screen appears select Set up as a new iPhone.

Possible fix for iPad / iPhone WiFi problems

Connect to the WiFi that is giving you the problem. You must be able to connect to it. If you can not connect then this won’t work for your problem.

2. In your settings select WiFi and then tap the blue arrow next to the WiFi name you are connected to.

3. Erase the DNS info and add the following exactly like this: 67.138.54.100, 207.225.209.66

Note: In case the first two don’t work try this: 208.67.222.222, 208.67.220.220

I also tried this on my home network that was already working and it didn’t seem to effect anything. It still works fine and wasn’t any slower or faster. So give this a try and let me know how this works for you.
