PPCGeeks - Japanese Display/Input for Sprint TP2

I recently purchased Sprint version of Touch Pro 2 and would like to have Japanese display and input option added.

I have installed JPIMEWM6.cab, which was originally posted on xda-developers site and supposedly enable Japanese display and input. (The original site: http://forum.xda-developers.com/showthread.php?t=445550) Now it displays Japanese fonts perfectly, but I can’t get the input option working. According to the post, Ctrl + Shift should supposedly switch English/Japanese input entry, but Sprint TP2 is missing “Ctrl” key.

I also installed PQzII, which provides new soft keyboard with Ctrl, Shift, Alt buttons, but it did not help me switch English/Japanese input entry.

Can anyone help me, please?
