Where is the send to phone button? Rated 3 out of 5 stars

The foxtophone used to be a very fine extension but recently I cannot find the send to phone buttion anymore!
I am using a Chinese version of Firefox 5 and have the extension updated to the most recent version. What is the problem??

This review is for a previous version of the add-on (1.1.2). 

We're sorry, in 1.3 the chinese translation is broken so the extension doesn't load at all.
The 1.3beta 1 at least should allow to load the extension, although it seems that the texts aren't displayed right, but we would need some help from a Chinese user to provide us with the correct version of the files.
