I've been sweating over my Reverb (discontinued..got it for $50). It was ICS out of box and I took the update for JB 4.1.2 and it really sucks. Running Linux Mint on my pc, couldn't find a root that worked. Tried Odin in Wine, jOdin (the linux port), Heimdall, towelroot, poot, and a million other possibilities. Finally got the word from Shabbypenguin to try saferoot.apk.
It works like a charm...
