I have a vita with 3.52 fw, so it could use that e-mail exploit, that's pretty useless to me, since I don't care about PSP emulation stuff. I'm trying not to update without a good reason, waiting for a miracle of a full Vita jailbreak. But now they giving Freedom Wars away in PS+ and I would like to try it. Buuuut, I'll have update fw and to lose acces to e-mail exploit. So, what do you think? Is this exploit worth to keep it? Or I should not want anything more than PSP emulation from and move on for now to play a game at least, vita don't have much of those, as anybody can tell.
