I was running my Hero (unrooted) on the first iteration of the 2.1 Sprint upgrade. I had not taken their first OTA update as I was planning to root my phone since the dialer lag was driving me CRAZY. I was really weighting my options with this phone as I heard that the dialer lag may not necessarily go away with rooting. Anyway, last week I bit the bullet and let the phone update OTA with the latest rev (dialer lag fix) and let me tell you, I feel as if I now have a brand new phone. I can't believe I can actually make phone calls with it and not have to wait 30-60 seconds for a call to go out. My phone just 'works'! By the way, I love the ability and freedom for me to root my phone and pick my own ROM, etc. I am not dinging rooting at all and I may one day root it. But as busy as I always am, and as much as I hated my 2.1 Hero all this time, I just wanted to say something positive in this forum about Sprint and HTC for putting this fix out there while other carriers have begun to end of life the Hero. This just breathed new life on my little friend and buys me more time before I get a new one as I am not particularly thrilled to buy a 4.3 inch behemoth. I have grown to appreciate the small size (easy on the pockets) of my phone and hope I can replace it with something of similar dimensions whenever its time to move on.
