Many people have wondered aloud what Sprint’s next big move might be after the Pre jumps off this weekend. The Palm Eos? Perhaps, but it looks like the struggling carrier might have something even more exciting in its bag within the next year or so. Market analysis firm SmarTrend is reporting that an unnamed Sprint spokesperson revealed a tri-mode handset coming down the pipeline sometime in 2009/2010. Said phone will be sporting CDMA, WiFi and WiMAX compatibility, which would provide a healthy mix of CDMA coverage and beastly data speeds where WiMAX is available. Analysts guess believe this upcoming tri-mode beast may be Android-powered, though we have yet to see anything substantiate that claim. As Sprint continues to expand WiMAX coverage and tout “the first wireless 4G network” in commercials, it would indeed be nice to see a handset emerge with WiMAX compatibility before the year is out. We shall see.
