I had given up on trying to get the certificate that gmail needs into the built-in Java on the Titan... Browsing through random stuff on the XDA-Developers site I found a CAB which was a newer version (Build 20070622.2.1). Worked like a charm...
So if you don't mind giving up the storage space to install it over the ROM version, here is where you get the CAB:

If we want to get fancy, we can try and determine which ROM files are the same and not overwrite those to save space... Also the executable could probably be UPXed to save some space.
