I heard from a Denver Sprint Store manager who had seen the 4920 mockup that its a candy bar form factor slightly shorter than the 4900 (which I have) with a keyboard similar to the RL2500. It's also a ready-link phone and reportedly tri-mode. "Spcssales" posted a message on Feb. 22 listing the tentative release dates for upcoming phones. The 4920 is scheduled for June.
phonerookie, go in the sprint forum and I've listed all the release dates for upcoming Sprint phones. As far as the 4920, I haven't seen it but I believe it's supposed to be a slim-downed version of the 4900. I am waiting on the new 8200...new version of 8100. I have the this phone. Did you know that the 8100 was the best selling phone of all time for Sprint? When it first released, they said they we're selling over 50,000 units a week nationwide!
