These instructions are to get your iPhone to use OpenDNS's DNS servers.
These instructions only work for Wi-Fi connections because iOS does not allow you to change the DNS servers when connected to cellular networks. Also, the changes are network specific, so you'll need to change the DNS servers every time you connect to a new wireless network. The good news is that iOS remembers the settings, so you won't have to do anything the second time you connect to a network.
Note: This works the same on all iOS devices, so the screenshots below show an iPad as it's easier to see.
Here's how to change your iPhone's DNS servers:
- From the iPhone's home screen, tap Settings.
- Tap Wi-Fi. The available wireless networks in range of your iPhone appear, as shown below.
Find your wireless network in the list, and then click the arrow. The screen shown below appears.
Tap the DNS field.
Delete the current DNS servers, and enter the new DNS servers. (If you enter more than one DNS server, be sure sure to separate the servers with commas.)
For OpenDNS, enter
