Hi, I did a search, but couldn't find an answer -- please direct me to one if I missed it. Anyway, I use Apple Mail with multiple Gmail accounts all set up using IMAP. Works great. I read a message, it is marked unread in both Apple Mail and the Gmail web interface. All is in sync. I had the iPhone 3G S automatically get my Apple Mail settings so that I could use my Gmail accounts on my iPhone (via IMAP, I thought). Settings migrated over just fine. I was able to see my email on the iPhone now. But, the syncing is not working correctly. I thought that when I read a message on my iPhone that it would be reflected in Apple Mail. But no, it is not working. I have to actually close Apple Mail to get the updated "read/unread" status. So, for example, if I have 10 unread messages in both iPhone and Apple Mail, and I read 3 on the iPhone -- I get 7 on the iPhone, but Apple Mail still stays at 10 indefinitely. Is this a known problem, or am I missing something? Thanks!
