Myself and others have worked hard to create applications which can disable data connectivity on CDMA (Verizon) Droid devices. Thus far, no one has been able to make it work. Sadly, because official Android CDMA support was not available for Verizon, Verizon wrote their own Android CDMA hooks. In doing so, it appears they have created a serious incompatibility with all other Android releases. As such, this portion of WiSyncPlus' functionality does not work on Droid.
At this time, WiSyncPlus does work on 2.0 and 2.01 Android images running on the emulator. According to Motorola, the images I'm using are the official images which they endorse for Droid/Milestone developers. As such, I can only conclude the incompatibility stems from Verizon's CDMA implementation. Furthermore, browsing of available source does seem to confirm full compatibility exists in readily available sources.
Hopefully the large Droid update rumored to take place in January includes Verizon dropping their broken CDMA+APN implementation and adoption of the official CDMA framework. In doing so, I fully expect WiSyncPlus to begin working, if and when, Verizon pushes the official and fully compatible CDMA+APN framework to their customers.
At this time, all testing indicates WiSyncPlus fully works on Android 2.x and later. On Droid phones, only APN toggling (carrier provided Internet) does not work. Accordingly, WiSyncPlus still provides some value to Droid users.
I can only hope Verizon's Droid incompatibility is not the shape of Android to come. If so, Android will be a complete failure. Keep your fingers crossed that Verizon fully intends to fix their incompatibilities in the very near future.
