Had the same issue! Called Sprint and they remove it from my bill. They also blocked all third parties from adding anything to my account without my permission.
Hey guys, I am new here or should I say I have been trolling for some time.
To answer the question of battery replacement I found a battery through sprint store.
Its been great to get a bit more time on my phone! It was cheap enough!
Mugen Power Sprint (CDMA) HTC HERO 200 1800mAh Extended...
I spoke to a rep on Tuesday that stated it was the 16th which has now passed!
I would like to see 2.1 before I start hacking on this new phone!
I must say though....I love my Hero! :D
