There are a number of lib packages in the repos that show as having updates (using FAPMAN, setting to show all), but when trying to install them shows them as conflicting with, and requiring the removal of mp-fremantle-002-pr 10.2010.19-1.002. This is obviously undesirable. However, there are others out there with N900s who have this installed without a conflict (or who haven't reported having one when installing the libs. particularly any of the libsdl-mixer libs.).

So my questions are thus:
1) how broken would my phone be if i actually let it uninstall mp-fremantle-002-pr?
2) Is there a way to get them to install/upgrade without uninstalling mp-fremantle?
3) is there a different/newer version of the metapackage that would allow me to install them that i need to flash to to be able to have the upgraded libraries so i can have all the games and aps i want?
