I have a jailbroken 2.2 3G and when I receive another call while on a current call it will not let me switch and put the first person on hold. It will let me end the call and switch but not hold the other person. The option bubble pops up but it will not let me select hold current call and answer the new one. Anybody have this problem??? Any help? I have restored and jailbroke more than once and this is still happening. Thanks.
