Thanks, I'll open it up and take a look at the connections - maybe the screws need a bit more tightening.
They both cost around £25 and it's all made of plastic - painted plastic although the XDA case is certainly better quality than the htc design.
I still have the HTC housing which is 'as new'. I'll sell it for £20 if anyone's interested.
Also the original comes in 6 parts, front, back, back antenna cover, battery cover, keypad, and central pcb mount.
