OK, so I tried copying over the phonecanvas.dll I extracted from the 3.56 ROM and that seemed to work with the Touch dialer. Data arrow, ##, are tested and working. This is using the 20273 kitchen from PPCkitchen.org
The smart dial still doesn’t work, but I installed the HTC smart dial again, and it seems to work ok.
I haven’t tried 911 though. I assume that it should still work as were using the stock rom dll, but I don’t know for sure.
Is there anything else I should test to make sure that it hasn’t screwed anything up?
