I have made substantial progress with Android Blackbook since its initial release on the 24th of June. It was released soon after as a pro verion, and has gone through over 150 verisions. Last Thursday was the release of the Moto Droid X. On this day the first wave of Demo versions began to expire. Many of the pro level features have already been ported to the demo version, and as new updates for the pro are published selected features will be made temporarily available for demo use.
Call filtering and sms filtering both appear to be quite stable at this time. There are still some kinks to work out of the UI, particularly effecting app stability. Have no doubt that the app is extremely stable at this time, but there are always new things to tweak and add. As of today I know of several things I need to address. Tonight I will focus on improving app stability.
I really want to finish MMS support, but why start a new, extremely complicated, feature when there are many needed stability issues to tweak to perfection. While MMS support is 90% done, I need to focus on making sure the app NEVER crashes and performs perfectly. Then and only then will I add MMS support. I expect this to be soon.
