So I updated to 3.0. I like it. Cut and paste is slick. I like the new searching on Email and searching overall. The new push notification thing in apps works well. Haven't tried tethering, and I have no use for MMS, nor a new 3G iPhone. The voice memo thing seems a bit useless - but maybe I'm just not the type who likes voice memos. The upgrade to 3.0 and then the jailbreak and unlock with "redsn0w" went really easily - and then a couple of clicks later got back my favorite "SBSettings" and Backgrounder functionality.
