I've successfully installed v1.72 V2 on my Nokia E52.
There is a major problem with the sound volume control: it doesn't work.
Any hint or fix?
uf, the answer is simple: The "7" key does not control the volume, but the "Volume boot" (gain) - if you want to turn the volume up or down, use navi-key left and right.
The "7" and "8" keys respectively turn the boost level down or up.
