If it's not locked, then you are ready to go.
There are two methods really, one is to go back to 2.1, root then unlock.
Another one is to use azuzu's kernel downgrade/upgrade to do it.
If you think you are a noob, then I'll recommend you to use the 2.1 method, as you won't be horrified when your phone gets stuck at the white SE text.
Once unlocked, flash back to 2.3, let it boot, then flash one of the rooting kernels from DooMLoRD, xRecovery is included and you can flash custom roms.
