Hi guys, My HD5 firmware is currently at 1.0 as I brought it the day it came out. I am interested in updating to 1.2 to combat the frequent crashes but the offical Sony site says its intended target is HD5's with 1.1. Will this matter or to I have to update to 1.1 first? If so where do I it? Also will I def have to backup my music or will this be safe during the update? (Otherwise I will have about 15 gig to backup!) Thanks!
