So, I feel like I am screwed. I had a similar setup, 1.4.111 running on a server, and now my iPhone is running 2.0. There seemed to be issues connecting to the server, and there was a dead device in Camera Backup list (which was I believe the previous instance of iPhone running 1.4.x sync). I could not get past the first screen when launching 2.0 post upgrade, could only link an existing or assume it was a new device. I did the new device just to get past that screen. I decided to unlink and uninstall everything and start fresh. Installed Sync 2.0 on iPhone, sent link to my email, and now when opening on 1.4.111 server, says I have to upgrade to 2.0. Please advise. I no longer have a working system, as my server runs Windows Home Server (Windows Server 2003) and 2.0 no longer supports that OS version.
