The company started signing up enterprise accounts last October using software that runs on BlackBerry devices from RIM, with Good's secure e-mail servers.
Good now boasts 20 enterprise wireless e-mail accounts, and announced yesterday that it would expand its offering with its own wireless data device, the G100, and an enterprise data access server, called GoodInfo, this summer. Good will also support devices from Palm and the Microsoft Pocket PC platform, said Good chief executive officer Daniel Shader.
While Good argues that its method is easier for users because no synchronisation is needed to access all Exchange functions, RIM officials say they have not made all functions wireless to reduce the cost of airtime.
"You don't want to do big bulk syncs wirelessly in order save bandwidth," Mike Lazaridis, RIM founder and president. He said that Good is "not a threat" to RIM and its announcement is "overblown" since every feature Good has announced will soon be provided by RIM.
RIM supports Lotus Domino and Notes, as well as Exchange. In terms of other technology comparisons, analysts noted that RIM provides a voice capability in its 5810 model that Good's device will not. Good functions over the Mobitex network, while BlackBerry users can choose four different networks.
At present, RIM requires synchronisation to a laptop or desktop to delete e-mails or to gain access to Exchange address or the memo pad function.
RIM has 321,000 BlackBerry e-mail subscribers, a number some industry observers find relatively small but still important..
