I think your math is a little off. a 0.5 V drop across 2200 ohms is about 0.25 mA not 2 mA. This is also what I measured using a 2K resistor in series with an ammeter. Just FYI.

Hmmm. Just got one of these. Looking at the data sheet the supply voltage clearly states 2.7 - 3.3 Volts. So why are you powering these (in the above examples) with 5V. Trying to sell more :). These examples really ought to be fixed.
No public wish lists :(
