We have created Conference Core.
BinPress.com component projects for Android/PhoneGap and iOS/PhoneGap.
While originally designed for meetings and conferences either project would make a good starting point for many other types of PhoneGap apps that require pre-populated SQLite driven databases.
A starter app that is designed to be used in conjunction with conferences or meetings.
The instructions that accompany the code are (hopefully) a useful guide on how to use pre-populated SQLite databases within PhoneGap apps.
