BlackBerrySync got the scoop on Sprint-Nextel CEO Dan Hesse’s speech at CTIA, where he said they’ll be replacing the iDEN-capable 7100i with a new BlackBerry equipped with iDEN and Wi-Fi. Though they’ve been on the ball with other BlackBerry releases, iDEN-capable phones have been pushed to the wayside. The 7100i was originally released way, way back in October of 2005. Push-To-Talk features — which is what iDEN does best — aren’t exactly deal-breakers to most people, I know, but two and a half years between releases seems a little excessive. There’s no word yet on what model they’ll be replacing it with, so we’ll have to wait on the details.
