Well I recently got a 20 GB ipod which is working great aside from two minor problems: 1- It never stops charging... I've had it plugged in for WELL over 4 hours and the battery indicator is still moving from left to right. It does hold a charge though.. 2- When I have it in it's dock and connected to my pb via firewire, it has that "Do not disconnect" thing flashing about 95% of the time. This could be normal, but I thought I'd ask anyway.. Also, in regards to calibrating the battery on pbs.. I've read both that you should do it three times, and that it needs to be done only once.. can anyone varify either of those? And should I put it to sleed while it recharges during calibration? Or is it ok to use..? Thanks... Oh and as an aside to those of you wondering about new 12" pb battery life.. I'm getting about 3.5 hours listening to itunes and surfing the net with airport on, bluetooth off and brightness usually on the 2-3rd lowest setting.
