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.
