I notice most of the discussions about Blackberry database options are old, and generally not too informative.

As of today, March 31st, 2010, what is the best, most universally supported, free database option available for Blackberry developers?

I heard SQLite is available for JDE v5, but last I checked, that was still in beta, and I didn't want to commit to developing on a system that is not supported by most of the phones in service. Thing is, I don't see any dates on these claims. For all I know, the announcements I am reading are from 2008.

So, I am still on v 4.7. I need to use a relational DB for the app I am developing, but there aren't many resources for DB handling available - or at least resources that are useful to me. I find a lot of "tutorials" that assume you know everything there is to know about Blackberry development, or Java. But no complete classes or anything. Many of these examples don't even work. Eclipse gives warnings and errors from code copied and pasted from other people's examples.

I can answer any questions that may assist in this case. Hopefully, this thread will help many BB developers in the future.
