Gmail fans, look over here, the simplified version now supports IMAP.

In October of last year, Google added IMAP support to the English version of Gmail and promised to open it to all language interfaces within a few weeks.

If you switched to the English version because the Simplified Chinese version of Gmail did not support IMAP, you can switch back now, as Google has added IMAP support to the multilingual interfaces of Gmail (including Traditional and Simplified Chinese). Just log in to your Gmail and click on "Settings" at the top right.
