After Motorola's big event today, we didn't figure much of anything else interesting would be going on. We were wrong - numerous sources have confirmed to TheVerge that Amazon is legitimately, actually working on a smartphone. We totally pretended to call it.
Those same sources say that Amazon's phone is yet to be totally finished, but that we may see a prototype tomorrow at Amazon's event in Los Angeles. They've also confirmed it runs a variant of an expected-to-be-announced Android 4.0-based Kindle Fire OS, which makes sense. That means no Google services, which definitely would put it at a disadvantage compared to, well, almost everything on the market.
