the step counter in my iPhone

not only gets the steps-to-miles conversion way off for me (if I look at its "miles" and read the distance as kilometers, it's about right), it doesn't even count the steps correctly. I just did a counted-off 110 steps (for another reason) and they were counted as 88 (starting count 94, finishing count 182).

This is no big deal for me in terms of wanting the data (when cattitude's employer sent him home with a free FitBit, I realized I didn't want to use one, without ever strapping it on), but seems worth noting.
