The HTC Hero and Samsung Moment (both Sprint) are EOL as of July 2010. No 2.2 or future upgrades for those devices. I expect this to continue with future phones. I've had a Sprint store employee basically tell me that they expect you to get a new phone every two years because things change so rapidly. But I just got my phone in May. So two months later, no new upgrades.
