Installing is an easy case by any way (with or without developer mode), but be very patient with it on a first run, as it takes 1 and half minutes after restart before it appears on stand-by screen (in my phone) ... if you are using other pic (like by LPM Customizer) on your stand-by screen, it will change that pic too, after 1 minute plus - well, it is hijacking, is it ? (laugh) ... after a first run, it will be always on your stand-by screen ...

I just tested 1.1 deb too (installed without developer mode, just for testing) - it works great too

Well, even I tested it without developer mode, I always suggest to keep developer mode enabled (no true point to disable it) ...
