In June of 2007 they said the OS was 16.6B. It's now 21.8B.
They reduced the share count, then during a time that the company claimed it was funded by third parties, it was diluted it right back to where it was and then some- well past any 800M figure.
While the reduction was a good thing, for a company that has supposedly been funded by deep pocketed outside parties for the past 4 years, it's a bit odd that they've needed to dilute the share structure from 16.6B to 21.8B.
