(keitai-l) I-mode technical information- from where?

Thanks everyone for interesting information about mobile life in Japan.
I'm currently planning to develope some tools with a bunch of other
interested developers for SMS and wap -services, and we were also
wondering about including support for i-mode. 

Could someone pointout the best places to get technical information
about i-mode -- cHtml, possible scripting languages, available tools,
i-mode phone emulators, specs of phones, limitations of phones
memory-screen-or-whatever that should also be considered etc. 

This would really help us and possibly save us time from inventing the
wheel again.
