Visto Brings Secure Corporate Email to Apple iPhone in Europe

Mobile Email and Corporate Directory Search Offered for Business
Professionals Wherever the iPhone is Available

London, November 7 2007 -Visto, the leading provider of secure and
easy-to-use mobile email for business and consumers, today announced that
it will provide access to corporate mobile email on the Apple iPhone across
Europe. Closely following on the heels of the availability of Visto Mobile
for the iPhone in the US, the company has extended its support to those
regions that are actively selling and promoting the iPhone.

Using Visto Mobile, iPhone users will be able to securely and easily access
push corporate email without downloading any additional software to the
iPhone or requiring any changes to security policies or corporate firewall
settings.

"The iPhone has come out of the gate faster than any other smartphone in
history and has broadened the market extensively with a form factor and
user interface that provides a better "all in one" experience than anything
else on the market today," said Brian Bogosian, president, chairman and CEO
of Visto. "For business users whose personal requirements and tastes extend
beyond the Blackberry device, we have enabled a solution that marries the
demand for corporate email with all the advantages the iPhone brings to an
individual."

Visto Mobile takes advantage of the iPhone user interface so that users
will be able to send and receive attachments, receive rich HTML email and
view emails as they were originally sent. And with the corporate directory
search capability, individuals can search for any contact and either place
a call, send an email or obtain driving directions by selecting the
contact's phone number, email address or physical address.

Visto Mobile for iPhone is available on Friday for both individuals and
enterprises and is free for 60 days. European pricing will be announced
shortly. Consumers can obtain more information and register to use the
service at http://www.vistomobile.com/iphone
