@GreatMarko: thx for the link. The file was not listed on the page, but your direct link worked fine. @RomanZ: Yes, I am aware. It was for my own amusement. Pretty much the only app that I miss on BB10. I tried .56 yesterday and with a read/write key file created on the phone would sync to my server fine. Files created on the server would not sync properly to the phone. Funny thing that btsync would create a multi MB file on the phone (the original was 7 bytes) and would show download/upload activity at 10..20 bytes per sec. So, seems like I could only use btsync for backing up files from the phone, but not for syncing. Just tried .63 with the same result. Both times I had to reboot my phone to delete the files that were created. I will wait for the next BB10 release (10.3.1) and hope thy would improve Android compatibility.
