China United Telecommunications (China Unicom), the country\u2019s second-largest mobile operator, has introduced a push e-mail service with a name that closely echoes Research In Motion\u2019s (RIM\u2019s) popular BlackBerry service."China Unicom\u2019s RedBerry brand not only incorporates people\u2019s familiarity with the BlackBerry brand name, but it also fully embodies the symbolic meanings of China Unicom\u2019s new red logo," the company said, describing BlackBerry as the most successful application of push e-mail technology.RIM is in talks with China Unicom\u2019s main rival, China Mobile Communications, to launch the BlackBerry service in China. RIM executives were not available to comment on the similarity between the brand names. China Unicom\u2019s new logo resembles a decorative Chinese knot, called a "pan chang," that traditionally symbolizes the bond and connection between people. That meaning has been adapted to symbolize the infinite connection possibilities offered by modern telecommunications networks and the bright prospects and longevity of China Unicom\u2019s business, it said.The RedBerry service allows users to send and receive e-mails containing up to 5,000 words and a 100KB attachment, the company said. The standard RedBerry package costs 5 renminbi (US$0.62) per month and includes a mailbox with a 5MB capacity. Each e-mail costs 0.30 renminbi to send, while incoming e-mails are free.There are two other packages available, including the high-end business package, which costs 30 renminbi per month and includes a mailbox with a 200MB capacity. This package allows a user to send 100 e-mails per month for free, with each additional e-mail costing 0.10 renminbi to send. Incoming e-mails are free.-Sumner Lemon, IDG News ServiceFor CIO\u2019s past coverage of the highly publicized court battle between RIM and NTP, visit our BlackBerry on the Edge page.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
