I have a couple of questions about the iPhone's syncing and E-Mail. 1. If I have a Gmail account (with IMAP), if I check new e-mails on my iPhone, will they be considered "read" on other devices (such as the Gmail Account on my MacBook Pro)? 2. If I have my phone set to sync my Contacts and I accidentally deleted all my contacts off my Mac, will my iPhone then lose all its contacts the next time I sync it? Thanks in advance.
