OK.....this charger (from my 7230) charged the Bold to 100% with no problems.
No Heat Issues either with the charger or the BB
After charging to 100%, the indicator light on the charger continued to
blink red....so I'm not sure if that's an issue or not, but the unit appeared to charge normally.
The Bold also went into clock mode when the charger was plugged in, so I'm guessing that everything was normal.
So....there you have it!!
