Here is the way to change the homekeys IN TFLO 3D.
In a registry editor, go to:
HKLM/Software/HTC/manila/
Here is:
HomeLSKPath, which is the left softkey (Standard = Phonepad)
And
HomeRSKPath, which is the right softkey.
If you change these with the location of the programs you want to link to, and simultaneous change the names:
HomeLSKText = Left softkey text
And
HomeRSKText = Right softkey text.
