I need some advice. After jailbreaking and unlock my iphone using ziphone 3.0, i've noticed that whenever there is incoming sms, there is no alert/sound. It's like it is in silent mode. There is no vibrate either. I did a full restore after that and tried again but to no avail. All other sound works (incoming call etc) but sms sound not working. I've tried resetting all settings but the problem still there. Any help would be greatly appreciated. Thanks.
