Actually, they just released IMAP.

For those wondering why this is so good:

It's because IMAP is a two-way e-mail protocol. IMAP client applications can interact with IMAP servers, like Gmail's, so data on both sides stays in sync. If you have multiple IMAP client applications, they'll all show the same e-mail messages (and indicate which messages have been read) as long as they stay connected.

LA, the rollout is taking a few days, not everyone can do it immediately. I doubt you're doing anything wrong.

here is a tip if you want to get rid of that extra [Gmail] hierarchy. Go in to your advanced email settigns and for "IMAP Path Prefix" type [Gmail] now go back and reassign your Sent, Deleted, and Draft mail boxes, if needed.

Sounds awesome!

Quick question though: will this screw up my email functionality if I'm using T-mobile's $5.99 internet plan?

I vaguely remember having to go through a couple extra steps to get that to work. The last thing I want to do it ruin it.

For those running firewall (eg: Office), you have to open up the port 993 and 587.
