Somebody mentioned here he/she has SQLite 3 working on Pocket PC. Could you please send the sources or diffs?
The 3.0.3 version is available at http://sqlite-wince.sf.net/
No interprocess database locking implemented yet, and there are still some unresolved issues with Unicode database open (use pure ascii paths). I am hopping this will be addressed in 3.0.5.
