If you aren't rooted, there hasn't been any update for Gingerbread for the Thunderbolt yet. Hang in there! Or just root and start messing around with Gingerbread right away with a new custom ROM. :)
I'll wait until the full release comes out to upgrade. I'm really enjoying the BAMF Remix 2.1 with Sense 3.0 add-in's right now.
I'm very excited for it though!
Re: [Auto] Root and Unroot (Windows)**Updated**5/20** w/MR1 updat
Just used the Auto Root on my Thunderbolt last night. Really easy and worked well. I then flashed the BAMF 2.1 GingeRemix and it worked perfectly. I thought I would run into many more problems but I really haven't seen any...
