-Kazuo Demo Works on 2.70, contrary to what Sony says.
-'pspnet_ap_dialog_dummy.p rx' & 'usbgps_serial.prx' removed with the update - maybe an exploit was found?
-They could have waited until 2.80 to release such a small fix.
This is different from the "OMG THERE IS A 2.71 UPDATE TRHEaDasdd!" therefore it is in the eLoader and 2.01+ Homebrew Discussion forum.
