As you may have heard, it has released a patch for PS Vita the version of the firmware is 1.52. And many feared would be a patch against security holes in the PSP emulator But now it is “confirmed” that this is not the case so you can patch in peace and quiet (But my source are not 100%). I will return when i get better information about it and its 100% confirmed.
It should be added that they have now managed to fix HBL at the European version of PS Vita!
