This is lame on Sony's part. They need to fix that problem ASAP. The controller is a real shitty design starting off with the fact that you cannot replace the battery to the fact that you have to resync it with USB plugged in. Now a bluetooth deadzone issue? Come on!
The Xbox 360 controller design is simple and well planned out. replaceable batteries, no wired sync, and 2.4ghz wireless works great. I have yet to experience a "deadzone" while playing.
