Query: COMPLETE CRAP

DO NOT USE JustWireless chargers with your Motorola Droid!!!! Horror stories galore... Just Wireless chargers cause my Droid to completely freeze up while charging on them... And NOW, my Droid is having residual effects from this when not charging. It froze up three times today (wouldn't wake up when I went to unlock the screen - it just remained black and I had to pull the battery out to get it to reboot!)
