I have a problem with a blue tooth stereo headset (Motorola S9) and multitasking. Playing music withthe headset attached is fine Untill you start too multitask (brickbreaker is a prime example) The task starts then locks up the entire blackberry. Upon a hard reset I receive a 523 error. This is a repeatable problem. I've actualy been told too Return my handset for a replacement. Problem is there are no replacements available in The entire country. Hope there is a patch for this bug soon As normaly these things are caught in beta.
