The update will remove the VCAST Music pre-load from the phone, while pre-loading the Amazon MP3 app. The Motorola Terms and Conditions screen will automatically enable data collection/location details, and a Google security patch is added to block access to change Home panel icon. After a factory reset, a location consent screen will show on the activation screen, and the "Terms and Condition" screen will have the new title of "Motorola Terms of Service".
Motorola DROID BIONIC owners are hopeful that the update will fix the data drops that have plagued the handset along with the "Black Screen of Death". And just perhaps the next "soak test" for the Motorola DROID BIONIC will be for Android 4.0.
