After many ftrustrated users because old iphone cables no longer worked after a firmware update (even the well-prised and known cable from DealExtreme stopped working (they send me 2 different cables built differently fot trying).).
Now Apple seems to have sorted out the issues, at least now an Official TV composite cable for Iphone3G is OUT!
I have just ordered one for myself and will report here whether it works or whether it does not!
Update: The cable works! The first one apple sent had unfortunately a broken wire but the 2nd one works without any problems! 🙂
