I'll hedge my bets with the manufacturer who openly released their Kernel Source Code to the public, like HTC did with the Thunderbolt, as opposed to the one who is trying everything they can to make sure theirs is as locked down as it can possibly be.Or you could just get the one with the unlocked bootloader and not have to worry about when Verizon considers the EOL to be....Having to keep a device for two years... I'd rather have technology in my device at the time of purchase that hasn't yet met it's full potential. This, IMO will help delay the EOL for the device.
Just sayin...
Here is to hoping it remains unlocked, nothing is keeping htc or vzw for sending an ota to lock and encrypt it.
For that reason, I can't imagine HTC releasing an OTA to lock the bootloader, or ever allowing Verizon to do the same.
