You, knc1, helped me a lot with your prompt responses! Thank you.
update:
Just to let you know, I repeated the whole JB process and for step *7* updated the jailbreaked PW3 to the actual 5.8.5.0.2 firmware.
Everything works like a charm now - including the KUAL kindlet, KPV booklet and all the other goodies! :-)
thx again to knc1 and encol
