I just upgraded from 1.1.4 to 2.1 using QuickPwn.
Open SSH from Cydia is also installed but winscp cannot connect to the phone
with the error "server unexpectedly closed network connection".
I have tried to uninstall and reinstall, rebooted the phone, without success.
If I Install open ssh from Installer everything works fine with winscp
but my target is to use Cydia
