I'm currently waiting for the unrevoked 3.2 tool to be re-released, and was wondering, for someone like me that just wants a simple root, what's the difference between unrevoked 3 and unrevoked forever? What will one get me over the other?
Thats what I was looking for. Is forever required to flash custom roms, or just "unofficial" ones that are unsigned?
No. Forever just means that even if the current exploits to attain root are patched in future software updates, your phone will still be able to load a custom recovery utility, so you can still flash roms (which can give you back root access).
