Hey guys, after having my P3S for a month and the price drop, I got the P3A today. Everythings charging up now, just trying to figure out which firmware to get. Since its brand new, Im assuming i can install whichever firmware i want. Should I install 1.3,1.5 or go straight to 1.6. Ive heard of some problems with the newest one, but not sure if thats the majority.
