have all my sounds (phone, email, SMS and MMS) set to ring while in holster. Except the phone does not ring when in the holster. I upgraded to .148 last night and have reset (battery pull) twice since then and still no ring while in holster.
i have been having this issue as well. its sporadic though. sometimes i get sound, sometimes i dont. ive wiped and reloaded and that still doesnt fix it. it also seems to mostly be the text message tone, although i will say that since ive started using a tone i downloaded and have on the sd card that it hasnt happened as much so you may want to try that.
