Hibino: Is that a fix just for my number? I told my friend who also using Defy and she sent a message to my vodafone and it still blank.
It's a fix for any handset that sends DCS 11. If hers is doing something different (e.g. sending DCS 9) then it won't work for her. I can check her too if you PM me the number.
Edit - if hers is the one I think it is, she's sending DCS 27...
Edit 2 - 27 means 16 bit characters with message class "TE specific". Weird.
I could apply a similar fix here but it might pay to check she has no strange settings turned on in her handset first.
