Public domain works still not available on iPhone - forgotten by Logos?

There are three PD resources that have been out a while and are still not available on iPhone/Mobile Web/Biblia yet, while many other recently released PD resources go straight to iPhone (within a week, of course).

Boyce and Miley have been out for 7 months, and Bannerman's work has been out for 9 months.  Have they been forgotten by those who prepare the books for the mobile environment?
