I'm only seeing the T-Mobile version when logged into the developer marketplace:

"Note: The device sold on the developer site is compatible with most 3G networks, including T-Mobile in the US. However, there are some carriers that have different 3G frequencies, such as AT&T in the US and Rogers Wireless in Canada, so users with these SIM cards can only access 2G or EDGE networks on their Nexus One. If you have questions about 3G compatibility for the Nexus One please contact your Mobile Network Operator. The 3G frequencies supported by this version of the phone are 3 UMTS Bands (900/AWS/2100 MHz)."

"GSM/EDGE (850, 900, 1800, 1900 MHz)"
