I just bought a palm treo 680 because i needed a new phone and it was fairly cheap and looked really good. I have charged it for a while and it seems about full. Even when i was charging my phone the light was red. The light has been constantly red for about an hour and i dont know if there could be something wrong with the phone it works fine but the indicator light has worried me a bit. Pease explain why it is red and thank you.
