Today MetroPCS announced that they'll be offering MetroPCS customers a version of the Samung r450 Messager custom designed by artist Mister Cartoon. The phone will have a custom backplate, custom colors, and will be pre-loaded with Mister Cartoon wallpapers, ringtones and animations. MetroPCS is auctioning off 10 of the handsets (for charity), which will be signed by Mister Cartoon. There will then be a limited production run of 30,000 of the customized handsets. The Mister Cartoon r450 Messager will be available later this month. Pricing wasn't disclosed.
