Thanks. Here's the short version of what I learned:
Put SDConfig.txt in the root of your SD card.
Edit it to add cabs to install.
Put an XML file somewhere that SDConfig.txt points to.
Edit it to make file-changes, reg-changes, and email-accounts.
(for each email account, be sure to make a
GUID)
Links to reg capture apps and other useful stuff are in the thread just above the first [ code ] block.
