SetDNS is the easiest way to force your rooted phone to use custom nameservers on WiFi for all devices AND 3G/mobile networks on rooted devices. Works for both IPv4 and IPv6 networks and nameservers.

JELLYBEAN 4.2 NOTE - THERE IS A PROBLEM SETTING WIFI IN JB 4.2 (certainly on Nexus 4). I WILL POST AN UPDATE AS SOON AS POSSIBLE.

Preserves your custom nameserver information when using both wireless and 3g/edge mobile connection. WIFI Only with non-rooted phones.
Comes with google, opendns, opendns family shield, fooldns settings, enter custom DNS servers and option to revert back to DHCP.
Includes widgets that will show the current DNS state and if you have DNS Pro installed, will allow nameserver changes by clicking the appropriate widget.
In normal mode, this app doesn't change *any* system files (unlike some DNS apps), so you don't need to back up your nameserver details. Just reverting back to DHCP will go back to your normal network settings.
You can update the resolv.conf file within the preferences if the normal settings don't work. This will modify the contents of the resolv.conf if it is writable, after taking a backup.
OpenDNS Family Shield settings can be used to filter adult or inappropriate content on the phone.
Using alternative nameservers like Google DNS or OpenDNS can dramatically speed up your browsing. You can also bypass local DNS filters such as Nawala.
Set DNS also checks if your browsing goes via a proxy service that overrides your DNS settings. When network settings change, it will try to access a URL directly using the IP address. If this hits the right server then you have a direct connection to the network. If not, then a proxy is intercepting the connection and is using it's own nameserver information.
Proxy testing is turned *off* by default. You can enable it in the preferences.
I've had some feedback about net.rmnet0.dns[12] not being changed (there's a comment here too). The app doesn't change these settings by design. Changing net.dns[12] is sufficient to change the DNS lookups on the device. However, if I get more requests for the rmnet0 settings to be changed, I'll add in an option to override the interface specific DNS as well. Just drop me an email.
====
If you have any problems with this - please email me or leave a message on the google plus page (see the About option) before rating on the market. Most problems are due to cached DNS or network proxies rather than the app itself.
In particular, testing against sites such as opendns will fail if going through a mobile carrier's proxy.

If you find this app useful, please consider buying the Set DNS Pro app which activates locking, control widgets and non-rooted functionality.

Please note, entering the wrong nameserver details can break your internet settings.

NON-ROOT FUCTIONALITY
If you install this on a non-rooted phone, please understand that some people are reporting in the market that it breaks their WiFi.
Unfortunately these people report the problem in the market yet don't get in touch with us so there's no way to resolve it. As a result, please consider the non-root functionality "beta" status and install on your device at your own risk.
