I just purchased an unlocked HTC Hero and plan on using it in the United States. I had a few questions about Android 2.0 and upgrading to it. I understand that the upgrade is not yet available for the Hero but when it is, is it going to be difficult for me to upgrade to the new software? Will HTC put out a release or am I going to have to use an unofficial version? Furthermore am I going to have to worry about locking my phone up everytime I do an upgrade or anything like that. (Think I-Phone firmware updates). Anyone that could answer would be greatly appreciated.
