A few months ago I was complaining about not being able to synch my iPhone with Snow Leopard Server. Today, I realized that email push wasn’t working either!

This ARS Technica article iPhone and Snow Leopard Server’s failure to communicate provides more detail.

Imagine if the iPod worked with a Windows machine but not on a Mac. Would make zero sense, right? Amazingly, this scenario describes the current reality with the iPhone and Apple’s server edition of its Mac OS X operating system.
