S60, UIQ = middleware + UI that are based on Symbian (note: Nokia even said
that S60 'supports' Symbian at one point)
MOAP = middleware, but not UI = Fujitsu + Mitsubishi UI are different from
SonyEricsson + Sharp UI AFAIK, but all four use MOAP-S
<plug> See here (http://visionmobile.com/blog/?p=13) and here
(http://visionmobile.com/blog/?p=20) for more details on Nokia's strategy vs
Symbian, including where Symbian ends and where S60 starts. </plug>
BREW = middleware + UI
AFAIK, all CDMA phones that are powered by Qualcomm chips (90%) use the
Qualcomm supplied operating system called DMSS or AMSS. BREW is a software
layer that sits on top of this operating system.
BTW, I found a slide that explains KDDI's BREW announcement very well:

Subject: (keitai-l) Re: KDDI_OS
S60, UIQ etc are said to be the user interface for Symbian OS.
How this fits into your definition?
BREW is said to sit between application and the software in ASIC, i.e.,
between application and the hardware. S60 has Symbian as its OS, what is the
OS upon which BREW sits then? Is it in the ASIC?
