i-mode features
The innovative i-mode service delivers a richer experience in connected mobile applications such as e-mail (iMail), web browsing and MMS (iMMS). Viewing multimedia is faster and easier, thanks to web content specially formulated for i-mode. Lighter pages give faster download speeds and end-users are given access to a host of i-mode sites and content, for example games, news and music.
  
A fundamental part of the i-mode service offering is Java content which is realized through DoJa, the name used to describe the specialized Java platform employed by i-mode. DoJa derived Java applications differ from the more familiar MIDlets by offering a different set of API and features. The end-user obtains content in much the same fashion as MIDlets where the provider can publish content which may be browsed and downloaded and installed directly via the phone browser.
