If your asking I say wait, there is obviously something about your phone that has you worried. If my phone was all set up just the way I wanted there is no way I'd do this update and start over...but it was only a couple weeks old and I was thinking about a reset anyway just to start over and fix it up the way I wanted, get rid of stuff I thought was cool and never used etc. Plus I was just feeling really geeky that day so I did it. Its really nice and I've seen some improvements, BUT those improvements are not worth it if its gonna take you 2 days to get the phone back the way you like it...my $0.02
