Disable all non-Wi-Fi Internet connections I want my phone (running Android 2.3.5) to only connect to the Internet via Wi-Fi.

How can I disable all non-Wi-Fi connections, such as 3G or similar?
This functionality is built into android so there's no need for an external tool/application.

In settings:

Wireless and networks -&gt; Mobile Networks -&gt; Data Enabled


Disable this and you're all set.
