3G Phones and E-mail?

SendItAllToOneAddress asks: "With the advent of the faster cellular phone networks, and an apparent lack of support for WAP among many popular web portals, I'm curious if the readers of Slashdot have a preferred way to retrieve e-mail by phone via Webmail or POP3 access, or are we stuck with the accounts provided by the cell services? I'd prefer not to have to use separate e-mail accounts, or to have to forward my e-mail to the cell phone."
