If anyone is interested in getting custom weather you can try this below as this has worked for me.
Disable Touchflo
copy the original 2330fc3c_manila database file from '\Windows' directory to your computer and change (uncheck) the read only property
Edit the database using SQL and the SQLite Administrator found here:
http://sqliteadmin.orbmu2k.de/
Once you have added all your places change properties back to read only and copy back to \Windows.
Delete the cache file located under \Application Data\HTC\Databases
and restart Touchflo.
This is what worked for me and I can now add the cities I customized in the database.
Hope this helps.
