Cingular pumps up wireless IM, e-mail.

"[Cingular] announced that it will offer e-mail and instant messaging from America Online, Yahoo and MSN on cell phones... Using a downloadable e-mail client powered by OZ Communications that converts the e-mail into a format that can be seen on the small screen, Cingular subscribers can access their personal e-mail from their phones. Unlike other e-mail services targeted at business customers that require expensive devices, such as Research In Motion's BlackBerry or Palm's Treo, Cingular customers will be able to use less-expensive cell phones from Cingular's current line-up."
