i've just arrived off the HTC boat and i'm lovin' the world of the Galaxy S2... what a phone!!
anyways, thought i'd make a thread on features as they get discovered as i tend to find that a lot go undocumented, and as i'm not a user of a previous version of Touchwiz, i'm not sure whether some of these are new or not, but maybe of interest to someone else like me...
