We previously caught wind of the HTC Arrive and Kyocera Echo. Now word is going around that Sprint might be gearing up to announce the Kyocera Echo at an event later today. Sprint’s tagline for the event is that it will deliver an industry first, though it wasn’t specifically mentioned what kind of feature/device that would be. Of course, there are also rumors that the HTC Arrive might be a CDMA Windows 7 device, and since there aren’t any such devices just yet, it might be what we’re going to get. Regardless of the rumors that are going around, we should be able to find out pretty soon, so stay tuned!
