Both ROM Manager and TB are working fine. Haven't downloaded a ROM yet but I installed CWM from ROM Manager no problem, and the downloadable roms are showing up fine. It also did a backup no problem.
As far as TB, like I said, there are some apps that just sit there and won't re-install, but they were VZ bloatware on my Bionic so they may not work anyway. Freeze worked, though it did not remove the icon from the app drawer. When you select the icon in the app drawer it does come up with "App not installed", so I had to manually remove the icons from my app drawer, but at least they are frozen.
I haven't had any issues with ROM Manager or TB really, so there must be something else going on.
