yes it can be jailbroken mate , but its a tethered jailbreak, which means if you have to reboot, turn off, or let the battery die , you will need redsn0w again to boot tethered and youll be back to normal again , look at this guide with links to what you will need
One thing i've always wondered, as i've never had a tethered jailbreak, if you do reboot the device will you lose all your cydia / installous apps? do they stay on the springboard? but maybe you just cant run them? or do they dissapear?
