Interesting I find this post after so long an the issue still exists. I have a 9900 on ATT with latest OS 7.1 (ans had same issue w all previous versions) When listening to Pandora, my BIS connection randomly disconetcs. Music still plays but messages and browser are left without connection. Toggling the radio on the phone off and on reconnects BIS, only so 5 mins later 's lost again. This behavior only occurs while listening to Pandora.
