The Nokia E72 is a smartphone from the Nokia Eseries range manufactured in Finland. The Nokia E72 was announced on June 15, 2009 at the Nokia Connections 2009 event in Singapore. It is the successor to the Nokia E71 and is based on a similar design and form factor, and offers a similar feature set. The Nokia E72 is a business-oriented phone (as all Eseries devices) and has standard features including mobile email, calendar and instant messaging among many others with its Symbian-based S60 3rd Edition Feature Pack 2 operating system.
The Nokia E72 has a new Optical Navi Key feature in addition to the standard D-pad used on many other Nokia devices including the Nokia E71 – this is said to improve the ease of scrolling through menus, emails, Internet browser, and images as it is an optical sensor in addition to a series of closely spaced buttons. In comparison to its predecessor, the Nokia E72 is said to have a higher level of performance (likely due to the faster 600 MHz ARM processor) and also includes a 5-megapixel auto focusing camera. Other changes and improvements are software-based including changes to the user interface and built-in messaging application among others.
The Nokia E73 Mode is a USA feature phone for T-Mobile USA, with support for T-Mobile's UMA service and Band IV support for 3G. It is a different piece of hardware internally from the E72.
The current firmware of this device is 91.004 published on 2 June 2012 (to check the current firmware, one may dial *#0000#).
The Vertu Constellation Quest from 2010 is based on the E72 design.
