We don't have a launch date for Sprint's crazy double-screened Echo
from Kyocera just yet, but this might be a bit of a clue: it just got FCC certification under its model number, M9300. The eternal optimist in us hoped for a last minute decision to throw WiMAX into the mix, but of course, no dice -- it's just a CDMA / EV-DO Rev. A radio along with 802.11b/g (no n, by the bye) and Bluetooth. The two screens is an interesting novelty, but we're dying to find out just how well that novelty translates into sales when it's finally on shelves.
