A tipster has confirmed to PreCentral that the Pre, or at least the WebOS emulator, supports IMAP IDLE for Gmail. What does that mean? Free push email for any Gmail account, basically. Color me impressed. [PreCentral—Thanks, Chad!]

Can't have "push" GMail as GMail doesn't do IMAP IDLE. It forcefully kills IDLE connections every so often...WinMo has support for IMAP IDLE, you don't see people praising the Push GMail support for it though...
