Here is what I have. I'm using the HHC download and simply moved it from my PC to my Touch and placed in the HHC clock folder then went into HHC selected the Diamond clock. The only problem i found was after a soft reset it said something like couldn't recognize the clock but started up fine and the Diamond clock loaded and functioned properly. I don't know what the cause is but it also says it can't find my carrier name b/c of customization but otherwise is working fine.
