The HTC Magic (aka Sapphire) is a touchscreen smartphone manufactured by HTC. It is known as the T-Mobile myTouch 3G in the USA, the Rogers HTC Magic in Canada, and the DoCoMo HT-03A in Japan. Its hardware (RAM, processor, internal storage) are fundamentally identical to the HTC Dream, but the Magic gives up the physical keyboard in favor of a touchscreen version and it has bigger storage memory (512 MB). As a result it is somewhat smaller, lighter and sleeker than the Dream.
Official CyanogenMod support was added in CyanogenMod 4.2
This devices is no longer supported after CyanogenMod 6.x
