Just got my E4 today. Already hacked it, didn't have courage todo the Menuhack yet, but will propably do that eventually.
BTW Firmware was still 1.19.8. Not sure about the caldate, where can i find that?
EDIT: Never mind. Turns out there's a cal certificate buried in all the paper stuff.
Cal-date is December 4, 2013
Cal-Site is Estonia
