The first Nokia E90 unit was sold in an auction in Jakarta, Indonesia on May 17, 2007 for Rp. 45,000,000 (5,000 US$). . Indonesia, being one of the largest market share for Nokia's communicator series, is cited as a reason for the unit's first launch location. 
E90 starts the fifth generation of Nokia's communicators, and also introduces a new platform to Nokia's communicator line, Series 60 v3. Previous communicators have been based on either GeOS or Series 80. E90 is also the first Nokia communicator to have UMTS/HSDPA connectivity and integrated GPS. It features OSGi and eRCP, Eclipse RCP for embedded systems.
