Re: iPhone 4: Visual Voicemail asks to be 'set up now' after each reboot

The fix:
Okay, I spoke with Apple Customer Support, and this is the detailed fix for the constant visual voicemail re-set after rebooting the iPhone (4). A warning though, it's going to use up a lot of your time!
1. Make sure that you've synched your iPhone, and have a computer back up (which includes all of your contacts, apps, email, photos, etc. - EVERYTHING.
2. Reset your iPhone 4 back to the factory default (this erases EVERYTHING from your iPhone). This is the "Restore" option found on the "Summary" tab in iTunes when your iPhone 4 is selected.
3. After step 2 is complete, when you are given the option to restore the iPhone either from a back-up, or start as a new iPhone, choose the new iPhone option (it's possible that your back-up has a "corruption" which lead to this problem).
4. Re-synch, and re-add all of your apps, movies, books, and photos, etc. You will have to redo any folders that you may have made (pain!).
5. You may have to update the phone's carrier settings (remember when you first got the phone?), by pressing a prompt on the phone if it tells you that a carrier update is available (download the update). The phone will also prompt you with the fact that it's now registered (with your carrier). This only takes a second (the shortest part of the whole process). Your visual voice mail should work. Your greeting may be set to "default", but if you choose "custom", your greeting should be there (push "play" to make sure). If not, then record a new one. My greeting was still there, and I didn't have to re-enter my password. All of my old messages were still there, too. Success!
6. You'll have to re-enter your wi-fi password in order to re-enable wi-fi.
7. You're done. It works. I've tested it, by restarting (re-booting) the iPhone 4 several times.
8. Go to bed, because it's late!
You're welcome!
