After reading the glowing reviews on the R4 I went out and bought one during my stay in Hong Kong. Since I didn't have access to a computer I never got a chance to use it over there. Once I got back to the states, I popped in my R4 and realized it was the Chinese version. I tried installing the Eng firmware but it didn't work. Is there a way to change the language back to English or is it just like the G6 where once you get the card with that language, that's it.
