do I really want to set up push

I've done every step on the Apple web site but when I was going to activate Push, I saw the following message.

Choose the data you would like pushed over-the-air to your device and tap “Save”. Important: When you press the “Sync” button, MobileMe will overwrite any existing contacts, calendars and bookmarks on your iPhone or iPod touch.

Now will that erase all my Favorites from my iPhone??? Will I have to reset them and their ring tones??

Thanks.

I did the push set up. Seems to have worked fine. It did the same thing yours did. I added a Calendar event on my iPhone, but nothing was pushed to my Mac. Any thoughts on how to do that??
