It appears that there is one of the runs of the device that is having the overheating issue. The overheating seems to be caused by a defect in the charging circuit. It over heats because the charging circuit is discharging so quickly it causes the device to heat up. We have had 5 in the past two weeks. I have spoken with verizon to see if they can start tracking these and see which run or runs of the 8530 are effected.
