Last night, T-Mobile and Samsung pushed out the Android 4.0 Ice Cream Sandwich update to the Samsung Galaxy S2. Aside from bringing in all the new features of Android 4.0, it also turns it into a fully IPv6 capable device.

With the Android 4.0 update, the Galaxy S2 from T-Mobile becomes the first branded phone to support T-Mobile’s new IPv6 network for HSPA+ (and eventually LTE). While the unlocked Nexus S and Galaxy Nexus from Samsung both offer IPv6 support with Android 4.0, they are not officially T-Mobile devices (though the company does offer some support for them).

If you have a Samsung Galaxy S2 from T-Mobile and are running it on T-Mobile’s network, you can easily turn it on. By going into Settings, tap “More…” under the Wireless and Network category, tap “Mobile networks,” then “Access Point Names,” then tap on the item for T-Mobile’s network. It should be called “T-Mobile US.” This will bring up a list of options to configure the APN. Scroll down until you see “APN protocol” and tap that. Select “IPv6.” Press the menu key and tap “Save.” After that, restart the phone and you should have IPv6 access on the cellular data network.

To switch back to IPv4, just repeat the process above and select “IPv4” instead of “IPv6.”

Note that if you use this phone with AT&T and try to configure an AT&T APN for IPv6, it will not work. AT&T has not deployed IPv6 for subscribers to use on the mobile network.

Detailed instructions with screenshots are available and more information about the IPv6 network is available at the IPv6 user trial website.
