There have been four major releases of S60: Series 60 (2001), Series 60 Second Edition (2002), S60 3rd Edition (2005) and S60 5th Edition (2008). Each release had an updated version called
Feature Pack, sometimes known as
relay. Each runs on top of a different Symbian OS version. ;Series 60 1st Edition: The devices' display resolution was fixed to 176×208. The
Siemens SX1 meanwhile had 176×220. • Version 0.9 was the original and first shipped with
Nokia 7650. • Version 1.2 (marketed as Feature Pack 1) first shipped with
Nokia 3600/3650 in 2003. ;Series 60 2nd Edition: Also known as S60v2. • Version 2 was the original and first shipped with
Nokia 6600. • Version 2.1 (Feature Pack 1) first came with
Nokia 6620. • Version 2.6 (Feature Pack 2) first came with
Nokia 6630. • Version 2.8 (Feature Pack 3) first started shipping with
Nokia N70 in September 2005. FP3 now supports multiple resolutions, i.e. Basic (176×208), and Double (352×416). The N90 was the first Series 60 device to support a higher resolution (352×416). ;S60 3rd Edition: S60v3 uses a hardened version of Symbian OS (v9.1), which has
mandatory code signing. In S60v3, a user may install only programs that have a certificate from a registered developer, unless the user disables that feature or modify the phone's firmware through third-party hacks that circumvent the mandatory signing restrictions. This makes software written for S60 1st Edition or 2nd Edition not binary-compatible with S60v3. • Version 3 was first introduced with
Nokia 3250 in 2006. • Version 3.1 (Feature Pack 1) first shipped with
Nokia N95. • Version 3.2 (Feature Pack 2) first shipped with
Nokia N78. :In 2006, a "Designed for S60 Devices" logo program for developers was launched. The logotype can be used with conforming programs regardless of them being native Symbian or Java. ;S60 5th Edition / Symbian^1: In October 2008 Symbian^1, also known as S60v5, was launched as the first OS under the Symbian Foundation, based on the S60 code so therefore also called S60 5th Edition. Nokia skipped the number 4 as they traditionally always do (due to
East Asian tetraphobia). S60 5th Edition runs on Symbian OS version 9.4. The major feature of 5th Edition is support for high-resolution 640×360 touchscreens; before 5th Edition, all S60 devices had a button-based user interface. S60 5th Edition also integrates standard
C/
C++ APIs and includes Adobe Flash Lite 3.0 with S60-specific ActionScript extensions that give Flash Lite developers access to phone features like contacts, text messaging, sensors and device location information (
GPS). : Despite the introduction of S60 5th Edition, the 3rd Edition continued to be marketed new as well, as 5th Edition is specially designed for, and exclusively available on touchscreens (e.g.
Nokia C6-00,
Sony Ericsson Satio). • Version 5 was first introduced with
Nokia 5800 XpressMusic in 2008. :S60 5th Edition was the last edition of S60. It was succeeded by Symbian^2 (based on
MOAP) and Symbian^3 in 2010. == Unification of Symbian interfaces ==
