I have an Iphone 4, on 4.3.3 via Pwnagetool on BB 1.59.00.

Since I upgraded to this firmware a few weeks ago, if I am on the phone in a call, and someone else calls me at the same time, and I hear it buzz through, if I lower the phone from my ear so I can see the number, the screen stays dark, and does not show the caller???

Has anyone else had this issue with this latest JB?
