Is there any difference between the two phones? Besides region and carriers? I was just wondering, cause I know Cyanogen is waiting for the source so he can get the sound working on his ROM.
The biggest difference seems to be that the Inspire uses a different sound amplifier than the Desire HD. The devs need to wait for HTC to release the kernel source code for the Inspire to see how to use this new amp compared to the old one in the Desire HD kernel. Once HTC releases the source code, the devs can start customizing this thing in earnest.
