Meh, I doubt Asurion has any Refurb'd 6800's just yet cause the device is so new. However I agree with drying it COMPLETELY. I dropped my 6700 in a puddle once and it died immediately. I yanked the battery out and took it home. At home I tore it apart completely and let it dry in front of a big fan. The screen took the longest to dry out... right around 22 hours. After it all was completely dry I slapped it all back together and she fired right up good as new.
I was so excited that it still worked... less than a week later I dropped it and the screen shattered.
Thanks for being there for me Asurion!
