T-Mobile adds WiFi calling to the Galaxy S2 via update

After the HTC Amaze 4G’s update recently, T-Mobile is showering the same kind of love on the Samsung Galaxy S II variant available on its network.  This update, like the one for the Amaze 4G, also adds WiFi calling among other fixes to improve battery life and caller ID.  The number to look out for is T989VUVKL1 to know if you are updated or not – of course, the base OS will stay at Android 2.3.5.

You know the drill on checking manually for updates if you don’t see the prompt already but you might want to give a bit more time before going ape and calling up T-Mobile about it.
