OpenWave browser

OpenWave was a Mobile web browser that ran on Misc Mobile OS. It was developed for about 7 years before being discontinued.

The first web browser for mobile phones. It originally used proprietary protocols but later switched to the WAP standard.

It was originally known as "UP.Browser", which was short for "Unwired Planet Browser".

In 2002 it seems to have become "OpenWave" browser.

There is a fascinating Quora answer (linked below) which details a lot of the details of the UP.Browser/Openwave heydays from someone who was actually employed by the company and who helped with the browser.

It's hard to find much information about OpenWave; either the history, status, or technical information about it. And the browser has changed name and technology a few times over the years so the lines blur a little bit...

PCMag's encyclopedia says that "In 2012, Openwave split off its messaging and mediation solutions into Openwave Messaging and Openwave Mobility, while reclaiming the Unwired Planet name for itself to focus strictly on patents.", so I think it's safe to say that the browser didn't exist after that point - it might have even been discontinued well before that.

However there is also a blog post (below) that notes in 2009 the SDKs became unavailable; so perhaps OpenWave ended then? This seems quite possible; even in 2009 WAP browsers were antiquated technology.
