it would cannablize Curve sales and thus be bad. Releasing devices on multiple carriers at the same time is bad for business, you would be fighting over the same customers. Notice that the GSM carriers in the states stagger the launches of devices, and push different features. For the same reason Sprint/Verizon *usually* have 30-90 days between launches. The devices for CDMA are upgraded when compared to their GSM bretheren. They already have 3G. And as a matter of point, the CDMA carriers released the pearl 2 series 6 months before any GSM carrier in the states. They dont always lag behind, it just appears they do, but the devices are newer when they come out.
