thanks for everything on here.
it seems like everything is ok when i flash clockwork, but i cannot get superuser to install on the phone. i'm able to run clockwork from recovery, follow the superuser install instructions, and see no errors with the install, but cannot find superuser when i look for it in the app folder. just to double check i ran a root checker and it came up negative.
i was in 2.2 with root and s-off, then just upgraded to 2.3.4 with s-off, and now want to root.
