I recently jailbroke my iPhone 3GS with blackra1n but did not unlock it at the time. I of course deleted blackra1n once the process was complete. I would now like to use this hack for tethering but I did not unlock the phone when I jailbroke it. Is it possible to unlock it now? I tried the hack without unlocking but it didn’t work.

you can download blacksn0w from Cydia by adding blackra1n repo

I was wondering if I would have to put an additional tethering package on my service plan or does this work with just the iPhone data plan ?
