+ depends how much ur paying for the 1.0 pspif its relatively cheap go for it
+now you can play homebrew on 2.0 and 2.0+ BUT not ALL homebrew and you have to have GTA to play homebrew on 2.01+ psps.
+the higher the version the more features it has, sony releases these updates
+Im not sure about thisone except that you can get a homebrew web browser but im not too sure cause i dont use it.
+ lol u sure can, u CANNOT downgrade from 2.01, 2.50, 2.60, 2.70 so if you update make sure you are completely sure you want it.. you can upgrade from 1.51 or 1.52 to 2.0 and then downgrade to 1.5.
hope that helped.. anyway more questions just ask
