So I haven't touched my Vita for (literally) exactly a year, and I'm interested in using it again. By some dumb struck of luck, I updated it to 3.18 and shoved it in my desk for a while, and now it turns out that firmware's useful. At this point though I'm not really interested in hacking it and would prefer to get a slim model, but I've never been in the PS Vita hacking scene so I'm not sure what I need to do to it before I sell it. Its got an 8GB card in it and my Playstation account. Can I deactivate that account on the Vita without messing up the FW? It would also be helpful to gauge how much this thing's actually worth. Thanks for your time.
