Froyo (and further) on Galaxy S

[Guest mastrociambella]

Hi, I've read that samsung uses encrypted drivers and strange partitions (as we're "tasting" with data moving from internal sd to nand),and that this makes porting from other phones impossible (or really hard).

Is that true? Does it mean that we won't have Froyo (and further upgrades,as foryo is the only one i think Samsung will realease) by cooks' work,without waiting for "company help" (that seems to be unfair,looking at past devices)?
