[Verizon Samsung Galaxy S III] MattBooth:
Didact... I've come to find that the HTC lockscreen works fine, so long as the weather is on? :/ If you turn the weather off in the settings then it breaks and looks like a blend of the AOSP and HTC and does nothing.

EDIT:

Got it working with and without the weather ;)

Make this change in:

\layout\keyguard_screen_htc_tab_unlock.xml

<Button android:layout_gravity="right" android:id="@id/emergencyCallButton" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="4.0dip" android:layout_marginRight="16.0dip" android:text="@string/lockscreen_emergency_call" android:drawableLeft="@drawable/lockscreen_emergency_button" android:drawablePadding="4.0dip" style="?android:attr/buttonBarButtonStyle" />
<RelativeLayout android:layout_width="fill_parent" android:layout_height="302.0dip">
<com.android.internal.widget.multiwaveview.GlowPadView android:gravity="bottom" android:orientation="horizontal" [COLOR="Red"][B]android:visibility="gone"[/B][/COLOR] android:id="@id/unlock_widget" android:focusable="true" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentBottom="true" android:innerRadius="@dimen/glowpadview_inner_radius" android:targetDescriptions="@array/lockscreen_target_descriptions_with_camera" android:directionDescriptions="@array/lockscreen_direction_descriptions" android:outerRingDrawable="@drawable/ic_lockscreen_outerring" android:pointDrawable="@drawable/ic_lockscreen_glowdot" android:glowRadius="@dimen/glowpadview_glow_radius" android:targetDrawables="@array/lockscreen_targets_with_camera" android:handleDrawable="@drawable/ic_lockscreen_handle" android:outerRadius="@dimen/glowpadview_target_placement_radius" android:vibrationDuration="20" android:snapMargin="@dimen/glowpadview_snap_margin" android:feedbackCount="1" />
<TextView android:textAppearance="?textAppearanceMedium" android:textSize="@dimen/keyguard_lockscreen_status_line_font_size" android:textColor="?textColorSecondary" android:ellipsize="marquee" android:gravity="center_horizontal" android:id="@id/carrier" android:visibility="gone" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="12.0dip" android:singleLine="true" android:layout_alignParentBottom="true" />
</RelativeLayout>
<LinearLayout android:gravity="center" android:orientation="horizontal" android:layout_width="fill_parent" android:weightSum="2.0" style="?android:attr/buttonBarStyle">
<Button android:textSize="@dimen/keyguard_lockscreen_status_line_font_size" android:layout_gravity="center_horizontal" android:id="@id/emergencyCallButton" android:visibility="gone" android:layout_width="0.0dip" android:layout_height="wrap_content" android:text="@string/lockscreen_emergency_call" android:drawableLeft="@drawable/lockscreen_emergency_button" android:drawablePadding="0.0dip" android:layout_weight="1.0" style="?android:attr/buttonBarButtonStyle" />
</LinearLayout>
<include android:layout_gravity="fill" android:id="@id/transport" android:layout_width="0.0dip" android:layout_height="0.0dip" android:layout_column="0" android:layout_row="0" android:layout_rowSpan="8" android:layout_columnSpan="1" layout="@layout/keyguard_honey_transport_control" />
</GridLayout>
</RelativeLayout>

And it works ok :)
