So far so good with 12.1.
No issues on install, and another excuse to help me tweak my Sashimi setup to restore my installs/settings after ROM flashes (not sure why Sashimi hasn't gotten more coverage in the Hermes forums... shrug).
Any way to update the screen caps in post #4? I have 25.91M free after soft-reset and that is with some stuff installed. For better or worse I think folks do shop ROMs by the advertised memory footprint.
Still trying to understand how the dialers work. Flashed over from the latest DVH ROM, and the dialer there had no good way to get to contacts (until you had made and terminated a call)...installed multiple other dialers (maybe they were just skins over the same functionality) and never could remedy. Very much like that this dialer has the Contacts button from the get-go (might seem silly, but its the little things in life)
