People are now able to update their PS Vita to Firmware 1.66. Firmware 1.66 is probably a simple regression bug fix from Firmware 1.65 unveiled yesterday, to address the “adhoc” issues people were seeing on PSP games.
Apparently, this firmware patches both Motorstorm and Everybody’s tennis exploits used to run VHBL(I haven’t tested yet). Update at your own risk. Reports also say that SKFU’s Vita pr0xy allows you to spoof your firmware version, in order to access the psn store without updating, so you don’t have to update immediately unless you need all of PSN’s services.
Thanks to everybody who let me know.
