Here is the cab for extending the Programs tab to 48 items.
I also seem to recall a cab out there to extend to 64... (edit: see post #12 below!)

Make sure you install the main 4ColumnsStart&AllPrograms cab in post #5 before using either of the "extend" cabs.

Note: The Extend_to_48_Items and Extend_to_64_Items cabs only work with Manila 2.1. (Don't install them on Manila 2.0.) Don't know how they work on 2.5 or Sense or any non-stock ROMs, but work fine on Manila 2.1 on a stock VzW WM 6.1 ROM.
