removing is easy with some small edits to the XML's,

1 - decompile the statusbar.

2 - goto the res/layout folder

3 - open the statusbar_tracking.xml file

4 - change the line with this

com.android.systemui.statusbar.phone.CarrierLabel

to include

** fixed now sry **

android:visibility="gone"

eg.

my file looks like this

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.statusbar.phone.TrackingVi ew android:orientation="vertical" android:paddingLeft="0.0px" android:paddingRight="0.0px" android:paddingBottom="0.0px" android:focusable="true" android:visibility="gone" android:descendantFocusability="afterDescendants"
xmlns:android="http://schemas.android.com/apk/res/android">
<FrameLayout android:background="@drawable/notification_tracking_bg" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1.0">
[B][I] <com.android.systemui.statusbar.phone.CarrierLab el android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="center" android:layout_gravity="bottom" android:paddingBottom="20.0dip" android:layout_width="fill_parent" android:layout_height="wrap_content" />
[/I][/B] </FrameLayout>
<com.android.systemui.statusbar.phone.CloseDragHan dle android:orientation="vertical" android:id="@id/close" android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageView android:layout_gravity="bottom" android:layout_width="fill_parent" android:layout_height="wrap_content" android:src="@drawable/status_bar_close_on" android:scaleType="fitXY" />
</com.android.systemui.statusbar.phone.CloseDragHand le>
</com.android.systemui.statusbar.phone.TrackingView>

turn it into this

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.statusbar.phone.TrackingVi ew android:orientation="vertical" android:paddingLeft="0.0px" android:paddingRight="0.0px" android:paddingBottom="0.0px" android:focusable="true" android:visibility="gone" android:descendantFocusability="afterDescendants"
xmlns:android="http://schemas.android.com/apk/res/android">
<FrameLayout android:background="@drawable/notification_tracking_bg" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1.0">
[B][I][COLOR="Red"] <com.android.systemui.statusbar.phone.CarrierLab el android:visibility="gone" android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="center" android:layout_gravity="bottom" android:paddingBottom="20.0dip" android:layout_width="fill_parent" android:layout_height="wrap_content" />
[/COLOR][/I][/B] </FrameLayout>
<com.android.systemui.statusbar.phone.CloseDragHan dle android:orientation="vertical" android:id="@id/close" android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageView android:layout_gravity="bottom" android:layout_width="fill_parent" android:layout_height="wrap_content" android:src="@drawable/status_bar_close_on" android:scaleType="fitXY" />
</com.android.systemui.statusbar.phone.CloseDragHand le>
</com.android.systemui.statusbar.phone.TrackingView>

that will hide the carrier lable, never to be seen again. it will also resize the notification are to be a bit bigger.

the reason you DO NOT delete the line is that the code can still update the carier lable when it needs to even tho it is invisible. if you delete it you would have to remove all the code that updates it too and that is a big job in smali... (far too hard)

Hope that helped.
