Okay, so I recently shut off my Edge plan, because it just wasn't worth it to me, being around wifi networks most of the time. Because of this, visual voicemail has been shut off, and I must use the old school voice mail. This would be fine, except it doesn't work right. When I choose the voicemail tab, a message comes up telling me it's not available, so I have to go to the keypad and hold down 1. Also, it never tells me how many voicemail messages I have, it just shows a red dot over the voicemail tab. Is there a way to fix this, it worked fine before I activated my iPhone officially (when I first got the iPhone, I hacktivated it to work with my old Cingular sim card). I've tried restoring, resetting, and I've even called AT&T with no luck at all.
