Some users of Google's web-based Gmail email service have noticed that Gmail is now offering IMAP access in addition to POP. (IMAP lets you check the state of your email from multiple clients without downloading everything at once, in addition to granting the use of folders.) This is especially good for clients that do not have phones for which Google has built a mobile client.
Because Google tends to roll out Gmail changes in waves, not everyone has access to IMAP yet—I don't—but rumor has it logging out and logging back in will sometimes activate the IMAP, the settings for which can be found under "Forwarding and POP/IMAP." If that doesn't work, you may join me in patiently waiting for the rolling tides of magic to wash upon our shore.
