My calls come in while chatting with Cingular, but a couple of times, with IM+, when I return to the chat, I have experienced a reset . . I don't believe that Sprint/Verizon will allow a call to come in while using data. I have seen several posts about calls being routed to voicemail on Sprint. Someone with sprint/verizon correct me if this isn't right . . .
