Visto's patented Visto Mobile platform will deliver a secure and easy-to-use push email experience to business users on the Treo 750v - the latest feature-packed, "business-ready" smart device from Palm.

"The immediate availability of Vodafone push email services on the Treo 750v demonstrates Visto's ongoing commitment to providing email on all leading business-ready handsets as they come to market," said Jean Tripier, Visto's executive vice-president and chief operating officer.

"The Treo 750v is a stylish, high-end device and we're delighted to be supporting it. Together with data security and ease-of-use, device choice is one of three core dimensions to driving the mass adoption of mobile email."

The Visto Mobile platform supports easy-to-use mobile email on more than 100 business-ready devices on all popular mobile operating systems, including Windows Mobile, Symbian and Java. It also supports all leading email systems, including Microsoft Exchange 5.5, 2000 and 2003, Lotus Domino R5.0, R6.0 and R6.5 and internet-based POP3 and IMAP4 services.
