Can I jailbrake it?

Hi guys

I'm looking at buying my first kindel, and this is the one I'm looking at. I dont have it yet... I'm going to place the order in 2-3 weeks when I get some money back (when my friend pays me the rent lol)

Now, I really want to install custom screen savers, as well as a few other things, so I want to jailbrake it. Does anyone know if its already done? or am I better waiting till after christmas and trying to get a paperwhite in the sales?

thanks
dan
