hans, going to do my best to sway you. here's the story of my most recent phone with htc
gingerbread was released in dec 2010 i think. thunderbolt launched in march or april with froyo, and that it would be updating to GB "soon". a month later, "soon" became "end of e2". the last day of june came along and nothing. no announcements. then there was rumors of end of summer. that came and nothing
they finally released the update in early october. here's the real kicker - the update they released was the same exact version developers already had their hands on for months. this version made it so voicemail notifications didn't work
yes, vzw pushed an update to our phones that made it so we never new when we got voicemails. they suspended that update, and released a working version late oct/early nov, 4 weeks later
i gave up waiting was running on gb through developers since summer. i still wanted the legit update for better performance. and it sucked. but in your case, not rooting your phone.. you would have been waiting all this time with no information. sound familar? at least with this gnex stuff, its only been a few weeks. imagine waiting for an update for 7-8 months
ontop of that, without rooting, your phone will eventually start running laggy on the rezound.. dual core or not. that's just how sense is
That, and the Droid Incredible JUST got Gingerbread not even a week ago.
Done with HTC.
