First of all  here is an explanation for four different Scenarios that you mite be in.

1.) If you have upgraded already to 4.01 then you are safe. Meaning you can still Jailbreak and UNLOCK your device.

2.) If you are still on 4.0 then you can also still Jailbreak and unlock using www.jailbreame.com.

3.) If you are still on a 3.xx firmware then you have to manually look for a 4.01 firmware and find  a way to install it to be able to Jailbreak and Unlock.

4.) If you are still on 3.xx firmware and you accidentally click update on itunes to 4.02 then you WILL NOT be able to use www.jailbreame.com anymore UNLESS you have your SHSH Blob back up on CYDIA which will then let you dowgrade back to 4.01 but you havent or dont understand what an SHSH Blob is then most likely you are stuck wioth 4.02.
