Most of you already know how to perform this procedure, but for those that don't, its simple.

NOTE: Unlocking your bootloader will perform a factory reset

Unlock Bootloader:
1. Open command prompt
2. Type 'adb reboot bootloader'
3. Type 'fastboot oem unlock'
4. Use volume keys to select 'yes, unlock bootloader'
5. Use power button to select option
6. Done!

Lock Bootloader:
1. Open command prompt
2. Type 'adb reboot bootloader'
3. Type 'fastboot oem lock'
4. Done!

Is there an icon, like there was with the padlock on the nexus one, after you unlock it?

On the Nexus S, you can do fastboot oem lock and it's like it never happened.

Where are you getting the Nexus drivers? When I select the USB driver folder in the SDK (fully updated) it just tells me that no drivers were found.

If I type fastboot devices I get the "unable to locate componant" error which says "this application has failed to start because AdbWinApi.dll was not found. Re-installing the application may fix the problem".
