The Sony Ericsson W950i is the third UIQ 3 smartphone based on Symbian OS v9.1. It was announced on February 13, 2006, a week after the announcement of the Sony Ericsson M600.
The W950 is Sony Ericsson's sixth Walkman phone. One of its distinguishing features is the 4 GB internal flash memory in which you can store many songs. However, it does not support any type of memory card.
Since the W950i is based upon the UIQ platform, it is easy to make third party applications that can be downloaded to the phone. Developers can choose their preferred programming language (Java, C++, etc.) and IDE (Visual Studio, CodeWarrior, Eclipse, Carbide, NetBeans).
