 Hi
 I hope this helps you all get started with phonegap and sqlite in your
 application

 <!--
 This is an example that shows how to create an application that uses
 an embedded sqlite database
 in a mobile device (iphone,ipod,ipad,android using phonegap, jquery
 and sqlite.

 Your phonegap project will already contain the phonegap.js.

 You will need to download and add to your project the jquery.min.js
 file

 The application will create a database called WebSqlDb with a
 table in it called User, which contains three fields  UserId,
 FirstName and LastName

 When the application is run the firsttime, if the local database does
 not exist, the application
 will create the database and the table.

 The application shows two text boxes which you can use to add values
 to the database using the add record button

 The application also has a refresh button which will get the data from
 the database and show it on the screen

 When the application is run on the device the onBodyLoad() function is
 called, which sets up the database and table

 The Add Record button calls the AddValueToDB() function

 The Refresh button calls the ListDBValues() function

 There are a few alert statements in this application, which are only
 there for debuggin purposes.  They look like this
 alert("DEBUGGING: followed by some text");

 These are only in the application to indicate where the application is
 at when it is processing functions, etc

 You will need to comment these out before you deploy/sell your
 application
