You can call the Sanyo Zio low-end, you can call it a remarkably good phone for $99, you can call it retro what with the trackball ...just don't call it Zay-Oh
or Zee-Oh. It's pronounced Zai-Oh, most Sprint reps pronounce it Zee-Oh, but we've also heard Zai-Oh on occasion. Obviously we'll be all over this very very important vowel issue in the coming days and months.
The Zio is light (almost too light) with a nice curve around the back and a matted finish surrounding that 3.2 megapixel camera. It's sporting Sprint's ID interface - which if you didn't hear is essentially Sprint's own custom Android skin that easily switches between branded experiences of your choice - from ESPN to Disney to your own small business if they're feeling ambitious.
More photos after the break - Update: check out the quick video demo after the break, which features the Lo2yo Latino Sprint ID screen. Update 2: video fixed. Mac Haters: feel free to mock iMovie.
