Once you've deleted the blackra1n.app, you have to restore in order to jailbreak it again. And you need to be on wifi to download and install Cydia, Rock or sn0w.
But when you restore, you automaticly update to 3.1.3 which can't be jailbroken. You can use a custom ipsw to update to 3.1.3 using the shift + restore method.
