Regarding root, not entirely familiar with how such a request could be made, and if I recall correctly they need to have a device on-hand, but I can certainly try and approach them (figure the worst they'll say is no). Having said that, these are all just perks for what's already a grand piece of kit. I've played with my fair share of gadgets (mobility and electronics are my thing) and there's little else I could ask from the package that Sony have offered, dated as it is. A Jellybean (JB; 4.1+) build may yield some battery and performance enhancements, but comparing the F-series to my Xperia Z I'm not seeing a difference in leaps and bounds. Now, I've read this thread from tip to tail and can't recall what was discussed. Were there supposed to be issues with the firmware update (my device is at 1.01...there's a 1.10, yeah)?
