This is my first HTC device and don't have any idea how well they support their devices with updates.
I agree in the least we will see ROMs of JB since HTC is so willing to allow root and I think the bootloader is even unlock-able. I just think this device could handle JB just fine and hope enough devices are sold to warrant it's development.
HTC didn't announce they will not be updating phones without more than 512mb RAM. They did not include the One V in the announcement at all. Then Engadget jumped to that conclusion on their own since it is true that they only listed devices with more than 512mb of RAM. Public pressure plus device popularity equals other possibilities. Their announcement was more to make those that shelled out alot more cash for their device happy and secure in their purchase. The profit margins on the One V is not likely any where near those that were listed.
I stand corrected thank you. I only saw the press release and never looked on their site.
