I have installed both the Desktop (Mac) version and the iPhone version. I believe I have followed all of the steps to allow the devices to synch based on the knowledge base and the forums. I've downloaded books in several different formats and have them open on my desktop in Stanza. I have Enable Sharing and Anonymous Sharing selected under the Tools menu. I've turned the firewall off on my Macbook Pro. It made no difference. I did verify that the firewall had Stanza listed as allowing connections. However, when I go to launch the iPhone version on my Touch, after double clicking the Stanza icon, the screen goes black and nothing happens. I am returned to the icon screen. I get no errors and the Touch does not re-boot as I had previously seen. I'm running version iPhone version 2.01. I've removed the app from my Touch and re-installed it. If it matters, I just downloaded and installed the desktop and iPhone versions today.
