I am having a problem when my screen is locked and someone calls me, the call will come in and once I slide the slider to answer the call it will not allow me to answer the call. Once this happens I can make a call or receive a call but I hear nothing same thing happens when I call Voice Mail. This only happens when the screen is locked, and the only way for me to start receiving and making calls again is to respring, but once the screen locks again I have the same problem. Not sure if anyone else has had this problem but nothing I do seems to fix this problem.

Iphone 3G Unlocked and Jailbroken on TMobile

Thanks
