Sprint teased us about a new device coming at a magic-filled event just before Mobile World Congress, but that (the Kyocera Echo) didn’t seem to impress the bunch of you. They then took to Twitter shortly after Mobile World Congress to tease us about a new device, but that ended up being a Windows Phone 7 affair. Just as they did last year, though, Sprint’s looking to wait until CTIA to bring the goods. We can assume it’s Android-related, too, otherwise we probably wouldn’t have been invited to this event they’re holding. Things kick off March 22nd a bit after noon so be sure to mark your calendar as we’ll be on-hand to provide coverage.
