I lost a bunch of my contacts when upgrading to iPhone 4.2.1 -- anybody else have the same problem? I didn't notice until later, when I went to call somebody and their phone number was gone. Then I went to email somebody else, and their email address was gone. It looks like it kept all the contact names, just deleted some info.
Each time I sync my iPhone, it seems to overwrite the iPhone calendar items with my Macbook calendar items. I enter all my appointments, etc. on my iPhone and would like to make the iPhone overwrite the Macbook items. Does anybody know how to accomplish this?
