Amazon just might be building a smartphone, according to the Taiwan Economic News. It claims Amazon has ordered 5 million devices and will launch the phone in the middle of 2013.

This is one of those rumours that pops up every so often. It's not very reliably sourced, so we can't say that there's a phone coming with much certainty. Reports about an Amazon phone have been kicking around for a long time. Amazon has done well with the Kindle Fire. But a phone needs to be much more than its tablet is. And because that, we're hoping this rumour is actually just a rumour. [Taiwan Economic News via Engadget via 9to5Mac]
