Ahhhhh marketing agencies. Buy your clients dinner at the right restaurant and you can convince them to do almost anything. Case in point: The Mister Cartoon-branded Samsung r450 on its way to MetroPCS. On the back of marketing firm SA Studios Global, Samsung and MetroPCS have teamed with famed tattoo artist Mark Machado a.k.a. Mister Cartoon to release a limited edition SCH-r450. The handset will feature tattoo-centric wallpapers, ringtones and animations beneath a re-colored case complete with Mister Cartoon-designed graphics on the battery cover. We hope you’re ready to pounce on this bad boy, MetroPCS fans — only 30,010 of these gems will be assembled, with the first 10 to be signed by Mister Cartoon and auctioned off for charity.
