We've heard of a few sightings of a Sprint HTC Arrive running Mango and now one has been captured on film. WPCentral forum regular Coolaaron88 was in his local Sprint Store out in Vegas and stumbled upon the HTC Arrive running OS Version 7.10.7720.68.

We haven't heard anything official or unofficial from Sprint and finding the Arrive running Mango doesn't guarantee an impending release. As with the Verizon Trophy being spotted in the wild running Mango, we like the odds that Sprint will join the Mango crowd sooner than later.

Thanks again to Coolaaron88 for sending this in!
