Is anyone else having this issue? Ever since the OTA update yesterday, if I am on the phone and another call comes in, at that very moment, the current call I am on gets disconnected and I have to click either "answer" or "reject" button. Its like the WAITING part of call waiting doesn't work anymore. like the phone can only handle 1 call at a time.. I've tried rebooting but dont know what else to try... Thoughts?
