Great news: the original Android 2.1 firmware
for Sprint's HTC Hero was recently rooted. Bad news: Sprint and HTC were entirely too quick about fixing it, pushing out an over-the-air update this weekend that patches up the so-called "security vulnerability" without a new root yet in sight. Owners of rooted devices are naturally being advised not to pull the trigger on the new build at this time; too bad HTC couldn't have shown this kind of hustle with the 2.1 upgrade in the first place, isn't it?
