i'm not comfortable not having at least a security patch update (have not received one since march!) however, there are some important differences as well. there are two types of driver exists, basic driver and full feature driver. i hope na decides to release these as well. it is though up to you. amateur video captured another suspect ordered to the ground quickly handcuffed by police. because i had someone who did it for me. actually, after messing with it for a while, i came back a couple hours later and it was working.
