It's that time of year again: The weather's getting colder, the leaves are changing colors, and rumors of an Amazon phone are emerging from their summer homes to terrorize the world once more. See also: Amazon phone launch live blog.

Both the Financial Times and Jessica Lessin are reporting that HTC and Amazon are pairing up to build the long-rumored Amazon smartphone. If the report holds any ounce of truth, the device is close to completion so it's only a matter of time before an Amazon employee leaves a prototype of the phone in a bar somewhere.

If Amazon is building a phone with HTC then it's a definite win-win for both parties: Amazon's Kindle Fires are some of the most successful Android tablets out there and it would only make sense for the company to move into the phone space with its own flavor of Android. HTC has long been struggling and recently posted significant losses, but the partnership would almost guarantee that a boat-load of HTC devices make their way to the hands of consumers--especially if earlier rumors hold true and Amazon offers the phone for free.

HTC declined to comment to TechHive about the report, and both companies declined to comment to the Financial Times or Jessica Lessin, so right now we can only speculate on what sorts of deals are happening behind the scenes. An Amazon phone running the company's own version of Android could just be the fastest way to customer's wallets but the big question remains: Would it come with a free year of Amazon Prime?
