My Cingular 8125 got dropped into my clothes bag yesterday afternoon while we were camping at Santee Lakes, and then I fogot about it. 

And when I got home later on Saturday, it was completely drained.  I tried to plug it in to re-charge via the external USB power cord but it wouldn’t come up.  It did however, take a charge from a USB cable to my Toshiba M400 TabletPC, so it is back to life now. 

But it was kinda weird the power cord didn’t work immediately (it works now that the battery has some juice).
