You're welcome @nevets2!
I really don't want to have to erase my phone and start from scratch, but if I have to, I guess I'll give in and do so. I know I can manually backup certain things and then copy/sync them back over, but I would prefer to find a fix.
Other than FaceTime, I can't say I've seen or experienced any other issues with my iPhone currently. iMessage works, iCloud works, amongst other apps and the like. Even my iCloud backup restored successfully (with the exception of FaceTime not working).
Even though it's months away, I'm wondering when Apple releases iOS 7, or if they release any other iOS updates, if that will correct the issue.
Based on this article, here is what is backed up and restored when using iCloud backup: http://support.apple.com/kb/PH2584
- Purchased music, movies, TV shows, apps, and books
- Photos and videos in your Camera Roll
- Device settings
- App data
- Home screen and app organization
- Messages (iMessage, SMS, and MMS)
- Ringtones
- Visual Voicemail
I am assuming one of the above items is what is causing FaceTime not to work correctly.
If I had to guess when this issue started, it was probably at the end of June 2013. The reason I say this is because I noticed my iPhone had a massive amount of "other data" (around 15 GB) when I was plugged in and checked iTunes. I was unable to find out what was occupying this space so I erased my phone and restored from my iCloud backup. This did indeed fix the massive amount of "other data" on my phone and things were seemingly fine until just recently when I tried to use FaceTime.
I do have files on my phone dating back to June 2009 (when I first got an iPhone) so perhaps it is time to erase and start from a clean slate, but it still seems funny to have to do so when it's only FaceTime that is exhibiting issues.
Earlier today I decided to see what I could see on my phone in the raw file system. I used the program iFunBox at http://www.i-funbox.com/
I am not Jailbroken but this program still allowed me to view some of the contents of my phone. I only saw one directory that looked out of place and deleted it but it did not correct my issue with FaceTime. I wish I had an erased/empty iPhone 4 that I can plug in to check what default contents are in the raw file system to compare with how my phone looks now. I am hoping that it is as simple as a corrupted file or directory that has to be deleted or, alternatively, if I have to copy and paste a file from a working iPhone from FaceTime back to my phone, that would be fine too.
