PS Vita Launches – Firmware Update 1.50 – System Software License Agreement | PS3Hax Network

a lil much to copy pasta, but i think i see why ... Neuron's discussing on her (his?) Twitter about a Vita Savegame Exploit. No indication if thats Launch 1.00 or Update 1.50

for the most part 1.50 adds PSN and the unlocked PSN related features,
