The PSVita has just got another firmware update to 3.69 once again this is just another useless update for PSVita/PSTV owners.
So does this update block anything that worked the previous FW? The answer to that is yes and no, this update does not block custom themes, PSTV Whitelist hack, VHBL, or the pboot bubbles, all of them still work just fine on FW 3.69. 
What they did block was the kernel exploit for 3.68 but they did not block the game exploit Bitter Smile which was used to trigger the kernel exploit. So if you are on 3.68 and like using H-Encore do not update as this might be the last exploit the PSVita sees for a long time but the Flow reports that they missed another bug.

So do not update to 3.69, plus it’s not like we are going to see a bunch of new games since Sony has dropped almost all support for the PSVita other than patching exploits.
