Regarding the autoconnect issues with the phone picking the MMS instead of normal one it's out of my control by the looks of it, one workaround is to use Havoc mode as this hides the MMS connection from the system. When uninstalling and removing the old access point used by fMMS manually with fAPN there is a high risk that fMMS will still try to use that connection after reinstalling as this settings persists even after uninstall; to clear all fMMS related settings you should write the following command in X-Terminal: gconftool-2 -R /apps/fmms and then reinstall fMMS.
