It is now being offered on the PocketInformant web site.
I'd say it was released a bit too early. I've just installed it, changed the font sizes and had it crash.
The install didn't prompt to uninstall the previous version. Also noticed that the installer prompts for the registration but doesn't pass it on to the program on the PPC, meaning you have to enter it again when running Pocket Informant for the first time.
I'm thinking of uninstalling and waiting for the service release that is sure to come in the next couple days.
