Inc S also supports CDMA.....

WCDMA
(Wideband Code Division Multiple Access)
Wideband CDMA is a third-generation (3G) wireless standard which utilizes one 5 MHz channel for both voice and data, initially offering data speeds up to 384 Kbps.
WCDMA is the 3G technology used in the US by AT&T and T-Mobile.
There are several newer technologies that offer much faster data speeds, such as HSDPA, HSUPA, and HSPA. These do not replace WCDMA, but rather build on and enhance WCDMA. Therefore any phone with HSDPA also includes WCDMA by definition.
WCDMA is also referred to as UMTS - the two terms are effectively interchangeable.
WCDMA is the 3G standard that most GSM carriers are moving to. Parts of the WCDMA standard are based on GSM technology. WCDMA networks are designed to integrate with GSM networks at certain levels. Most WCDMA phones include GSM as well, for backward compatibility.
WCDMA borrows certain technology ideas from CDMA, as the name implies, but is in fact very different and incompatible with phones and networks using "CDMA" technology.
In Europe and Asia, WCDMA is being deployed in the all-new 2100 MHz frequency band. In North America, WCDMA is being deployed in the existing 1900 MHz (PCS) and 850 MHz (cellular) bands, as well as the newer 1700 MHz (AWS) band.
Hope that clears it up. If the Incredible S was indeed CDMA compliant, why would they need the Incredible 2?
