Hi. I am wondering if we can change the timing at which Voicemail kicks in on the iPhone 3GS? According to my wife's experiment, the default timing seems to be set at 20 seconds even. However, all the ringtones she created are 30 seconds long, and she would like to be able to hear the whole ringtone. Looks like some carriers, such as Softbank in Japan, gives you that option. OTOH, I personally don't know of any way to do that with AT&T. Any help would be appreciated!
