Seems like you haven't picked up your Vita in a while... Do you know about HENkaku exclusively for 3.60?

And yes, there's already a new firmware that patches this out. (3.61), so be sure to block updates as well! (Or simply leave your Vita in flight mode when neccessary)
sigh... didn't see this and just let the thing update so i could buy a game i wanted to play. Now at 3.61.
