oh you work in a company that develops chipset
so its good that you are aware of each and everything
Sony promised ICS , umm 5-6 months back , and now they have started rolling out.
developing a whole new android version will take some time and its not that easy as releasing minor updates from time to time.
custom rom's - to use them one has to unlock the bootloader and if anything goes wrong , i agree , phone will be dead so that's why i haven't unlocked it yet. don't want to take any chances.
there are many custom roms which are good and trustworthy like cynoegmode ( something like that ) and the security issue , i agree one cannot ind out what information is going out from the device.
a big issue relating to this emerged a few months back.
as i said earlier , not an easy task to develop a new android version and adding their skin too it. whats the use of skinless version , you won't get company's goodies.
have you been to htc forum ? you should check that from time to time.
