Hello, I have an iphone 3gs and recently purchased the griffin autopilot car charger with aux out. I am loving this thing, it charges the phone and plays just fine, the only thing is, I noticed when the phone says it is 100% charged, the ring on the charger continues to glow amber, I have yet to see it turn green to verify the charge is complete, has anyone else noticed this with a iphone 3g or 3gs? I do realize this is a unsupported charger as it indicates the message when I plug it in. Just wondering if it may be overcharging the iphone and damaging it. Thanks in advance!
