Nice work, will test later. Is there any versions of ICR that correctly integrate into the HD2 Dialler (allow to start/stop recording in the dialler menu)?
Update: If you add some reg keys you can enable the record option on the dialler (will post later as on mobile) and it works very well. Just need to find out how to specify the download location
One thing i would say is don't activte recording till the call has connected as it seems to block the mic for me and reduce recording settings as these sound files eat up the device memory.
