San Jose, CA; USA, November 5, 2003 - DoOnGo Technologies, Inc., the market leader in mobile device software management and over-the-air (OTA) application provisioning, announced today that they have been working with NEC for the last two years and Sharp and Panasonic Mobile Communications for more than one year to ensure the successful launch of NTT DoCoMo, Inc.'s new service. NEC and Sharp already released the first commercialized handsets with OTA capabilities in October 2003.

"DoOnGo's primary focus has been on supporting our customers and making their handsets successful in order to maintain DoCoMo's high standards for reliability," said Luosheng Peng, CEO & Co-Founder of DoOnGo Technologies. "We are extremely proud to be a part of the world's first OTA launch and will do everything possible to make this a success for leading handset vendors."

Two years ago DoOnGo engaged with Japan's leading handset vendors, to provide DeltaRewrite, a cable based point-of-service and portal rewrite system that was available in NTT DoCoMo shops. This system proved its value and represented the critical first step in bringing an OTA system to market. NEC became a DeltaRewrite licensee in 2001 and Sharp and Panasonic Mobile Communications licensed DeltaRewrite in 2002. According to an article published in Nihon Keizai Shinbun on October 23, 2003 during a six-month period from 4/1/03 to 9/1/03, NEC, Panasonic Mobile Communications, and Sharp had a share of 23.7%, 16.7%, and 10.7%, respectively in the overall Japan market.

"We first engaged with DoOnGo in the development of DeltaRewrite for embedded software rewrite using the differential update technology that was released in the Spring of 2002. DoOnGo's software core technology proved its worth and allowed us to seamlessly move the software update technology from a point-of-service system to an OTA environment," said Mr. Koji Maeda, Senior Manager, Mobile Terminals Software Development Division, NEC Corporation. "We are now proud to announce our latest OTA capable handset model for DoCoMo's mova N252i."

"We started to engage with DoOnGo in the development of our mova handset that was released in 2002. DoOnGo's good customer care and support allowed Sharp to bring this first product to market on time," said Mr. Yoshiro Nakano, Department General Manager, Software Development Department, Personal Communication Systems Division I, Communication Systems Group, Sharp Corporation. "The use of DoOnGo's DeltaUpgrade software has allowed us to transition to an OTA update capability. We are now proud to announce our latest OTA capable handset model for DoCoMo's mova SH252i."
