So, I purchased my HOX on craigslist and the hboot was already upgraded to 1.23 (it was running ARHD v15.0). I know some of the downsides to upgrading your hboot (e.g., cannot flash AOSP JB roms without a special boot.img), but now that I'm already upgraded to 1.23, can anybody see any further downsides to going ahead and upgrading further to 1.36 (I have cid HTC_0.23) so at least I can flash the JB Sense roms?
