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.
Information on each release is available from Symbian's website: http://www.symbian.com/technology/product_descriptions.html
Information about what version is in each phone is available from manufacturer websites. Some information is available on
