Search results on Google, Yahoo, and Bing for "Sprint Playbook" indicate that a 4G model of RIM's BlackBerry tablet could be on the way soon.
The search results show a Web page with the title, "Sprint | Introducing the BlackBerry 4G Playbook Tablet," though the Web page itself shows nothing beyond the ordinary Sprint site.
Accompanying text snippets add a little more but don't reveal anything that hasn't already been announced: "Enjoy front and rear-facing HD cameras and a Flash-capable Web browser on the blazing-fast Sprint 4G network...The BlackBerry 4G PlayBook tablet arrives this summer," the Yahoo search result said.
Research in Motion currently sells only a Wi-Fi model of the PlayBook so far. A PlayBook for Sprint's 4G network is due this summer, RIM said at CES in January.
The PlayBook is geared in part for the corporate crowd that's been the core market for the BlackBerry phones. A 4G option, while costing more to purchase and operate, has the advantage of working where Wi-Fi isn't available, a big advantage for road warriors.
Sprint boasted last week that it has launched or announced 22 devices that use 4G, or fourth-generation, wireless networks. It's using a 4G technology called WiMax, but it appears that the rival LTE (Long-Term Evolution) will be more widely used.
