HTC Touch Diamond users can download an updated ROM for their device. Available here it fixes a number of bugs including the camera preview screen going black, video recording issues, audio playback, MMS receiving and sound issues on the Music tab within TouchFLO 3D.
This is a generic update, so those who have bought the Diamond through a network may have to wait until a branded version of this patch is available. As usual it’ll remove your personal data on the internal storage and a good battery charge is recommended.
