I am running 1.5..When I get a 2nd incoming call my phone does a lond double beep and cuts out current call..I can't hear the 1st caller and they can't hear me...Has anyone had this problem and if so how can I fix it...Verizon of course has never heard this complaint..I did a full reset...Even with just stock apps it does this..They offered to send me a refurb one...Any thoughts?
