Android is truly open-source -- wide open!
Well, wide open on the subset that are unblock{ed,able}, for the subset

Were can I download the source to Gmail and Google Docs?
Android is kinda lame without them. :)
I might be wrong, but I don't think Google/OHA ships the Android Gmail
app as part of the Android.com open source project.

Back to the original question, there's also a Python for WinCE-based
devices.

As well as for iPod, Palm, PSP, and Symbian S60.
