I love my original TBolt and have never had to replace it (even after numerous involuntary impact tests). I have suffered along with many here with the growing pains to be finally rewarded with the updates that finally took advantage of the hardware capabilities and Verizon LTE speeds that were originally promised. The temptations to root were strong but I just stayed the course with the stock setup and the updates as they were released. It was never a bad phone for me from day one. I didn't suffer many of the radio issues or reboots others went through. My battery life has always been livable since I have a charger at home, in the car and at work so I'm rarely dependent on the battery for more than a couple of hours at a time.
I'd like to get ICS on it and an updated version of Sense even if it isn't full 4.0. I actually like Sense which some people don't. I consider it a good starting point for a launcher/interface over the stock OS and have had no problems customizing my user experience with dozens of free aftermarket apps that have made this phone a remarkable daily companion.
My hope would be to see Verizon adopt something similar to the One X without effing it up or kludging it with too much of their bloatware and restrictions. I have a strong feeling whatever I replace my TBolt with is going to come from HTC and I'm probably going to root the new phone and get into a whole new ballgame going forward. Right now I'm not even looking for. nor envious of, anything else out there.
