PRESS RELEASE

WES 2010, Orlando, Fl., April 27, 2010 Cellcrypt (www.cellcrypt.com), the leading provider of secure mobile voice calling, today announced the availability of its high-strength government-grade encryption application for mobile devices, including BlackBerry' smartphones, on both T-Mobile's secure cellular network and T-Mobile's Wi-Fi' HotSpots across the globe. With encryption accredited to the FIPS 140-2 standard (approved by the U.S. National Institute of Standards and Technology), a government official or traveling executive can use their T-Mobile Wi-Fi-enabled BlackBerry smartphone to make classified or confidential calls and be assured that the content of their call is protected to government-level standards.

According to a recent study conducted by the Ponemon Institute entitled, "Security of Voice Data," it costs U.S. corporations on average $1.3M each time a corporate secret is revealed to unauthorized parties. For more than 60 percent of surveyed organizations, these breaches occur at least once per month.

"Any breach of proprietary enterprise or government information can be incredibly costly," said Simon Bransfield-Garth, CEO at Cellcrypt. "Now, business and government customers using T-Mobile's Wi-Fi-enabled BlackBerry smartphones with Cellcrypt's encryption application can add peace of mind to the cost and convenience benefits of Wi-Fi calling. In addition, Cellcrypt provides added security for calls placed over standard mobile networks."

The Cellcrypt easy-to-use mobile application provides end-to-end voice encryption on smartphones over the entire path between callers. Utilizing an IP data channel, it seamlessly protects and supports both Wi-Fi and 2.5G, 3G and 3.5G cellular networks.

"Across the enterprise, we are seeing as many as 1.6 million calls originated using Wi-Fi calling per month," David Pepe, Divisional Director, Government Sales at T-Mobile. "T-Mobile has put in place several security safeguards " from security algorithms and encryption keys on our Wi-Fi-enabled devices to an IPSec VPN tunnel to secure voice and data traffic between the core network and the device. For those customers desiring additional levels of security, Cellcrypt's government-grade encryption application makes secure calling as easy as placing a normal phone call."

Cellcrypt will be demonstrating its technology at WES 2010, at which it is a Silver Sponsor, in Orlando Fl. between 27-29 April 2010.
