With True Blood and other HBO series now available to watch through PSN, the premium cable television network is giving away six one-of-a-kind PSPs themed after Alan Ball's popular vampire/telepath/werewolf/shapeshifter-filled program.

Each of the branded True Blood PSPs features the show's logo and one of its principal characters: Sookie Stackhouse, Bill Compton, Jason Stackhouse, Eric Northman, Lafayette Reynolds, and Sam Merlotte (what, no Tara Thornton?). You can enter the contest on Facebook.

And if you want even more free True Blood PSP stuff, the PlayStation Blog posted a free voucher code last week for previewing the new True Blood digital comic. The code is available here, though you might want to read through the comments if you experience any issues with the download.
