If I use Samuri's script or whatnot to upgrade to the latest ICS leak from 905, will my daughter lose her high score and all her power-ups in Temple Run? Yes, yes. Silly question. But no, seriously: More broadly, will the data (settings and such) for all of my apps be preserved during this OS upgrade? Should I backup everything? Will that even work? That is, will TiBu or whatever even work on "recovery," since it will be an entirely new operating system (environment; dir structures, etc.)? Thanks for any info.
