Great news. Gmail has introduced support for IMAP, and according to the “what’s new” page:
Don’t fret if you don’t see “IMAP Access” yet under the Settings menu. We’re rolling it out to everyone over the next few days. #
So while it seems like everyone else seems to already have it, I’m still stuck in the dark ages here. I’ve waited for more than a few days, yet still no IMAP. C’mon Google, you’re killing me here.
