Secure Access to Corporate Email and the Corporate Directory Now Available for iPhone Users in the US

Redwood City, Calif., November 6, 2007 – Visto, the leading global provider of mobile email, today announced the availability of Visto Mobile™ for the Apple iPhone for individuals and corporate IT departments. iPhone users will be able to securely access push corporate email from Microsoft Outlook or Lotus Notes on their devices, without downloading any additional software to the iPhone or requiring any changes to security policies or corporate firewall settings.

“The iPhone has been a game-changing mobile device with unprecedented sales and consumer excitement,” said Doug Brackbill, Executive Vice President and CMO of Visto. “We are pleased to provide iPhone users with secure access to corporate email in addition to the many lifestyle applications that are already available with this device. With Visto Mobile, the iPhone becomes the single resource for an individual’s personal and professional needs.”

Visto is also announcing a new capability for the iPhone – directory lookup for the corporate directory.  Using the iPhone’s Safari web browser, this feature enables individuals to search for any contact and either place a call, send an email or get driving directions by selecting the contact’s phone number, email address or physical address.

“Visto Mobile provides Samson with an easy-to-use corporate email service that didn’t require any changes to our existing email infrastructure,” said Johnny Callison, Server and Storage Supervisor for Samson Investment.  “The Visto service took minutes to setup and the instructions were very easy to follow. Without Visto Mobile, we would not be able to give our iPhone users the critical email functionality that they need to perform their jobs.”

Visto Mobile takes advantage of the iPhone user interface as well as its existing email and phone features to deliver an easy-to-use, consistent experience that is optimized for the iPhone. Users will be able to send and receive attachments, receive rich HTML email and view emails as they were originally sent.

Visto Mobile for iPhone is available for both individuals and enterprises free for 60 days.  After 60 days, pricing will begin at $10 per device per month. Consumers can obtain more information and register to use the service at http://www.vistomobile.com/iphone .
