I had installed libimobiledevice-1.1.4-8 via fink on OSX,
and i wanted to backup my iphone with iOS 6.1.3,
command:
$ idevicebackup2 backup ~/Downloads/sandbox/backup/ Backup
directory is "/Users/mj/Downloads/sandbox/backup/"
Started "com.apple.mobilebackup2" service on port 51336.
Could not perform backup protocol version exchange, error code
-1
In ticket #320 (status: invalid) it says that iOS6 backups
should work with libimobiledevice version 1.1.4 or higher.
If its the case that I need 1.1.5 (latest unstable build), could
you please push that to fink?
Cheers
Markus
