The new handheld will not be using Opera's browser as the Nintendo DS did.
Access, a company who develops embedded software, will be providing a version of the NetFront browser for the Nintendo 3DS. The Internet browser will be available for download through a software update in May.
The Internet browser is currently in use in over one billion devices including mobile phones. Notable versions are those produced for Sony's PlayStation 3 and PlayStation Portable.
The Nintendo DS initially used an Opera provided and named Internet browser, which later lost the Opera name and was known simply as the Nintendo DS/DSi Browser.
