BIG PROBLEM:
App not working correctly. When accessing calendar in iphone, it freezes. See details at
http://nuevasync.blogspot.com/ They are working to solve but I had to do a "Reset All" in my settings to get rid of it. Big pain as this knocked out my Wifi. had to go into Linksys setup to reconfigure router for iphone as well as changing other settings back to previous configuration.
Called Apple for help and they talked me through the restoration issue which didn't solve the problem but did make everything else run much better.
