Visual Voicemail Not Working After iOS 4.0.1 Updateon 4 August 2010
I had no voicemail for a week. iOS 4.0.1 did something during the update that interfered with the voicemail download process.
I tried resetting all network settings, that did not fix the issue. The fix that did work was
System > Reset > Reset All Settings. This will reset all of the setting saved in the System app for all of the default Apple apps. Mail preferences (does not delete passwords, emails or accounts), Phone preferences, SMS settings etc.
One option I did not try was resetting my voicemail password on the AT&T website, and then having the phone prompt me to renter my password. I question, though, if it would have even prompted me to update it.
I at least visually have less bars in more places thanks to 4.0.1.
