Would like to know what devices are working well , and the ones once connected don't perform so well under OS 9 PB 1 , in my case , I found out that the Whitings scale , has to be coach a couple of times to be pair back with the phone , the app most likely needs to be updated , the KEVO lock no longer is recognized and the app crashes on opening , the Jawbone UP 24 band is not recognized ant the app crashes the phone completely . Now , my car ( Altima) has no problems connecting to the phone , neither are my wireless MPOW 3 bluetooth headsets , the Macbook air also connects without a problem. Although I do noticed some lag in connectivity .
