No we aren't.. Starburst has one patched by ownhere, though the one tried for Supernova was not a good one. I haven't used the one for Sense 3.5, but I've seen apps on the Market which check database operation speeds and can tell you whether it's any good. Can't remember the names of any of them now Sibere could tell you more..
However, that links back to a file posted on ownhere's original thread, which makes me wonder if it's the same one you guys tried with Supernova?
EDIT Actually, the patched libsqlite was posted in a CM7 (Android 2.3.7) LG Optimus thread, so its def not a Sense version! Oddly, seb15 said he'd installed it and it worked. Well, if I get around to trying it will let you guys know if it worked...not expecting much though
