Hey I'm just wondering. I'm sorta iffy about upgrading to this new CFW. I'm currently on 5.50 Prome-4 on a PSP-2001 and if I upgrade to the 6.xx CFW, would my savedata become corrupt. Also if I upgraded, would I be able to play demos downloaded from the PSN? Would there be any problems with DLC if I stayed on PRome-4?  On the 6.xx CFW, would I be able to load ISO's.  What I'm bassically asking is what are the advantages and disadvantages for upgrading to 6.xx CFW.

Sorry for asking so much, its just that school has kept me busy and I haven't been able to keep up with what's going on in the PSP scene.
