That is kind of interesting. I have a similar cradle/bluetooth issue. Whenever I put my phone in my Seidio cradle and try to use my bluetooth headset, my calls get cutoff within 10 seconds of connection. Sounds like there might be some relation to your problem. I have been through 3 Seidio cradles and I have the same problem on each of them. I can use a regular car charger fine but the cradle gives me issues. Try using a different charger is possible and see if that has any effect on your issue.
