Platform: Symbian OS v6.0, Symbian OS v6.1, Symbian OS v7.0, Symbian OS v7.0s, Symbian OS v8.0a, Symbian OS v8.0b, Symbian OS v8.1a, Symbian OS v8.1b

Question:
What Symbian OS versions are available?
What are the differences between them?
Is there a mapping from phone to Symbian OS version?


Answer:
The following Symbian OS versions have been publicly announced:
  • Symbian OS v6.0
  • Symbian OS v6.1
  • Symbian OS v7.0
  • Symbian OS v7.0s
  • Symbian OS v8.0 "a" and "b"
  • Symbian OS v8.1 "a" and "b"

Prior to Symbian OS v8 there was a single kernel architecture "EPOC Kernel Architecture 1" (EKA1). In version 8, a new "real time" kernel architecture was created (EKA2). The flavours of Symbian OS v8 - 8.0a, 8.0b, 8.1a, 8.1b reflect which kernel is present - "a" is for EKA1 and "b" is for EKA2. In future versions, the EKA1 kernel will be dropped in favour of EKA2 builds.
