using this tethering hack breaks the iphone's voicemail function. You won't get notified if you have a voicemail and for those who has visual voicemail, it wouldn't work too. I've tried to find of ways to get the both of them to work but to no avail.
Maybe it's just me or maybe someone could point out on how to fix this.
My VVM and notifications work fine with the tethering hack...
