There are 3 different aspects: -fastboot support in the bootloader: disabled (in theory) in consumer devices, enabled in ADP1 (restricted to system, boot, recovery, cache and userdata partitions, I think, i.e. stuff that can be flashed safely without bricking), enabled in engineering devices with no restrictions on partitions (i.e. can brick a device).
-root access in the system image. disallowed (in theory) in user builds (as used in consumer devices), allowed in userdebug builds (as in the ADP1) and engineering builds. -SIM locking. US G1s are configured to only work with T-Mobile SIMs (unless T-Mobile gives you an unlock code). Not sure about other retail devices. ADP1 and engineering devices can use any SIM. Notice that the first two aspects are somewhat tied: if you have fastboot access, you can flash a system that gives you root access, and if you have root access (and access to the right files) you can update the bootloader. Personally, I consider the second aspect to be a weakness.
