Telstra is the first local carrier to support the Good mobility suite of applications which includes mobile messaging, intranet, and Good's mobile "defense" software in an integrated offering.

Like the BlackBerry, Good Technology provides push e-mail and groupware, but it can be installed on a number of different mobile devices. Telstra will offer the solution on smartphones like Palm's Treo series, and the I-mate.

Telstra's managing director of convergent solutions and sales, Lynda O'Grady said the long-term arrangement with Good re-enforces Telstra's "leadership" in the local mobile e-mail market.

"Telstra is all about offering our customers the broadest choice in communications solutions," O'Grady said. "The Good mobility suite allows us to provide more tailored services to their unique business requirements."

IDC's mobile software program director, Stephen Drake, said the analyst firm estimates the Asia-Pacific market for mobile enterprise e-mail to be growing at a compound annual growth rate of 38.2 percent.
