I recently purchased a new 3GS from an At&t customer. It has never been used, never been activated - he sold it because he never ended up needing it. Will I still need to unlock it to use it on a different network?

i believe you will and it will also need a sim card installed.

and it'll need to be jailbroken too

yes you can jailbreak and unlock with the help of redsnow
