Samsung’s new Ultra Edition 8.4, also known as the Z370, has landed in Europe. Touted as the world’s thinnest 3G handset, the Ultra Edition 8.4 comes with a large 1.93″ TFT display, a 2 megapixel camera, and a regular VGA camera for video calls that were incorporated into an impossibly thin 0.3″ thin body. In addition to the Ultra Edition 8.4′s launch, Samsung also introduced the Ultra Edition 13.8 (Z720) which will reign as the world’s thinnest HSDPA slider phone. You’ve got to hand it to Samsung for claiming that title as it is also the only one of its kind. There is no word on a Stateside release at the moment, so keep your fingers crossed!
