Let me get this straight - I can use my Kindle 3 (keyboard) or DXG wall charger for the KFHD? Are you certain? Europe electricity is different, but the adapters are rated to include it when I charge the Kindles. I am a bit panicky about doing anything that might harm the unit!
Prime mostly doesn't work from European countries except UK, German, Italy and Spain (if I remember correctly). Only the book part. That's why we didn't mind my using the KFHD for awhile, and starting the 1-month "Prime".
I may just de-reg and not reset to factory and see what that does.
Thanks for your help!
