Not rooting any time soon
That's cool, I *highly* doubt the TBolt gets an ICS update. I could be wrong, but it's unlikely HTC/Verizon will want to invest the resources on it. Heck, they didn't even bother to put Sense 3.0 on the GB update...
Why would you not root? If you did you could install a custom ROM and would be able to have the quick settings in the notification bar you are looking for. You can always go back to stock. Warning once you flash a custom ROM it can be addicting.
I Agree 100%, but I don't like to try to "push" anyone into rooting that doesn't want to. There are definitely things to consider before taking that leap. The benefits of rooting are well documented, but it does require an acceptance of responsibility to maintain the phone, and the risk involved with voiding the warranty. For more on this, see the FAQ linked in my signature.
Maybe i will when there is a rom for 4.0 . I am happy with my phone as it is now. After the GB update today my phone has been buttery smooth. Something big like ICS needs to sway me into do it.
As much as I doubt that the Thunderbolt will ever "officially" get ICS, I'm pretty sure that some well-built ICS ROMs will start to pop up once the source code is available. I'm too spoiled by BAMF Forever to go back to stock, but if you're happy and the phone runs well, stick with it.
For me, I'm way to curious to not root. The Thunderbolt was my first Android device, and in the first week I owned it I was like "I don't really need to worry about rooting and all that"...but then I was literally rooted a week later, using ADB (no revolutionary method back then!). About a week after that, I was already scrapping the stock OS to install ROMs. I was hooked. For me, it's like an addiction.
