Max2893, rooting your phone gives you access to the phone that is denied by default. After rooting my phone, the first thing I did was remove the stupid preinstalled applications. I don't use Blockbuster or Twitter, why do I want those apps on my phone. Some apps require root privileges. I'd say the primary reason to root is to install 3rd party roms. If the issue from my original post gets resolved, you can install a rom that will allow Sync to read your text messages, without relying on the manufacturer to add that feature.
swoop1156, unfortunately I've never rooted a Thunderbolt. HTC has released a root tool for some of their phones, at Welcome to HTCdev, but it doesn't work for the Thunderbolt. I googled and found a bunch of links on how to do it. This one seemed to be a good walk through for a non-one-click method.
