The iOS 4 upgrade was done in 43 minutes, basically painless and trouble free.
The WordPress app 2.5 has been updated. The one I'm concerned about is whether there'll be new features such as Polar's WearLink+ pairing in the Nike+ app. Too bad it isn't there yet. What's bad is that all history is gone leaving me only total distance done and best km. I also have to calibrate it again.
