Motorola Backflip-The phone is built on the Android Platform, Android 1.5. Motorola recently announced that the Android 2.1 software update will not come out until Q3 2010.-The phone has most Google apps removed and replaced with AT&T and Yahoo applications which cannot be deleted or uninstalled (though AT&T and Yahoo apps can be easily removed from the homescreens and replaced with Google apps).-Apps can only be run from the marketplace and sideloading is disabled.-The phone comes with "MOTOBLUR" which cannot be uninstalled or disabled. Workarounds have been discovered, though it requires the user's computer in order to accomplish this.-It has a full QWERTY keypad with an unusual "reverse flip" design. When the device is closed and the screen is visible to the user, the reverse side is the keypad itself. Opening the device causes the screen to flip so that it rests above the keypad.

Architecture

Security

Applications run in a secure sandboxCannot read/write other applications data, network access, keeping device awake, make phone calls, etc

All applications are signed

Programming Environments

Dalvik

Custom Java runtime environment/virtual machineIncludes most of the core Java libraries and functionality, such as objects, trash collection, etcHas an eclipse ADT pluginDalvik is the primary/most powerful dev environmentNot for performance intensive operations

Ajax

Javascript is used to manipulate Document Object Model DOM Supports canvas (for drawing/graphics), gears, geo location, etcHTML5 support is in development and will be release in piecesCannot access graphics layerCannot access/start background processesCan be connect to Dalvik environment

Native Code (C)

Dalvik can run native codeFastest execution layer - best for mathamatical calculations, physics, loading large data files, etcCannot access graphics layerAll sandbox/security rules still apply
