A Good Embedded DB for Mobile Applications

I'm developing an App on windows mobile and android, i needed a database for this app and as of now have shortlisted 3 lite databases. SQLite Ultralite (from Sybase) Oracle Lite

of these 3, i was unable to configure UltraLite with my existing project on VS2008. i am currently using SQLite with the dll from http://sqlite.phxsoftware.com but i will need a embedded db that is a lot more data intensive. thus i tho开发者_JAVA百科ught of using Oracle Lite but i have no idea of the licensing or cost issues as far as Oracle Lite is concerned.

So now i have 2 questions:

1. Can anyone help me with configuring Ultralite for my VS2008 poject (i tried the tutorial - http://www.codeproject.com/KB/database/Win_Mobile5_Database_App.aspx but still keep on getting the error)

2. is there any LEGAL way i can use Oracle Lite for developing my mobile app for free, if not what are the costs?

It looks like you already have solved the issues in your first question.

Regarding your second question Oracle Lite is not free. You can see the prices here.
