If you use a SQLite3 db or so for preferences, you cannot access it from different packages, but in some cases you can implement an export/import mechanism, saving the preferences in a file into the external SD card.
My first app uses just a plain text file written into the SDCard and for having same preferences in free and in per pay versions I just need to use the same name for that file. Currently I use an SQLite database, so I cannot do that so direct. But to be honest I do not care. At least in my case it is not so important.
