First battery Charge gone WROng?

[MogulMongler]

Hello :

I got my Diamond from Assurion, and upon following the quick start instructions I noticed it recommended that you charge the phone for 12 hours I believe. That sounds crazy within itself, but what do I know about conditioning a battery.

The issue comes up with the fact that after 12 hours the little ring won't stop flashing. It won't move to a solid state, indicating a full charge.

Should I be concerned ???, I spoke to HTC, they said try and get it swapped at a Sprint store, Assurion was like play with the phone for a week or so, if it doesn't hold the charge, call back they'll swap it. & sprint was like F-U, and laughed at me.

Input, please.

Thx
