I remember seeing something before I got mine about an update for the DINC to have 720p recording as well as adding the "droid" boot screen. that never actually happened right? I didn't think it did but Engadget's post about Froyo for the DINC mentions this update like it had happened. All I know is I can't record in 720p and no drooooooid on my boot sequence
From my understanding, there was supposed to be an update but htc/Verizon decided to wait and roll it into the FroYo update instead so they'd only have to push one OTA instead of two.
The Leaked OTA is available for non-rooters if that scares you. But honestly Unrevoked has made rooting so simple compared to when I first had to do the SD-card shuffle. LOL...
