I'm always backing up my apps and whatnot with Titanium, so I can follow the instructions for the best possible flash (fresh)... but is it that detrimental to just flash this over the previous version? Are those just guidelines? If anyone could share some insight that'd be great. I've never really been clear on the issue.
Over & above the new features added, a lot of the changes that would affect stability (for d2) were to a2dp. There will likely never be an iterative version of Android that magically makes things substantially faster or "more" stable since it's already at that point, but regardless there is a lot of work that goes into each release. This is becoming more evident to the team as more & more ROMs start using ours as a base for theirs (Liquid/Carbon). It's flattering and proof that the Slim team is putting together a solid product.
