[Q] PS Vita Owners, please check in here about wifi hotspot topic

Ok so there's several topics out there that describe what's happening to me. I'm on 4.3, I turn on hotspot, everything works except PS Vita. It can connect, but not surf nor contact PSN. Has no actual connectivity. No tether/hotspot apps work either.

Some have said that 4.0 maybe 4.1 roms work. But I'm not really sure.

Anyone out there get this working and if so, what rom or fw version are you on? And did you have to do anything else special?
