Up until yesterday, I have been running on a PC/Windows-based system and had my iPhone 3G synching with my Windows' version of iTunes. I have a couple of questions about this transfer. Now that I'm solely running Mac/OS X, when I go to synch up my iPhone 3G for the first time to iTunes, is there something I need to do within iTunes to reformat or adjust it to the Mac/OS X platform or will it just format to Mac/OS X automatically. I remember when my wife had her MBP about a year ago there was some extra things she had to do within iTunes to tell her MacBook Pro that her iPod was now running under Mac (since she, like myself now, was a past-windows user). Also, when I synch my iPhone 3G to iTunes for the first time, will the contacts on my iPhone download and set up into Mail? If not, is it a situation where I have to manually enter each contact into Mail? Thanks!
