Note: maybe we discussed this earlier... I don't know. But, so what if he did. Would not iTunes post a warning that this restoration may not work? And why wouldn't it? Is this a known problem with iTunes/Apple, and if so, why isn't it caveated within iTunes?
Apologies if I babbled to you before about this.....
No you have not asked me about this.
No iTunes post no warning. It is suppose to work. But so are a lot of things in iTunes that simply don't work properly.
Have had fix friends iPhones before (never found out the exact problem) in which the only way to get the phones working properly again, was to setup as new after restore....multiple times they restored from an iOS 4 backup and certain problems arised. No specific problems. Stupid little stuff, syncing problems...and one case where more ten a few apps would crash.
After screwing around with the 2 phones I concluded that every time they restored from a backup from iOS 4, they would find a problem, and they would beg me to fix for them.
After convincing them to restore and setup as new(which none of them wanted to do) there was no problems at all. phones worked fine, synced fine, no apps crashing...no lagginess, and no missing stock icons or preferences.
I'm not saying if you restore to iOS 5 from an iOS 4 backup that it "will" cause problems....I am saying that you have a higher chance of having problems when restoring to iOS 5 from an iOS 4 backup.
From my personal experience......it is a better idea to start on a new iOS fresh (not new iOS, but a new iOS genre). Especially one with such Changes that iOS 5 has.
Why wouldn't iTunes post a warning: that's easy...because Apple expects there it be no problems (as usual). And perhaps depending on what your iOS 4 backup actually contains, it could work just fine....and quite the opposite. My guess is that it depends on what your iOS 4 backup contains. the more data you have the higher the chances for problems. The less data in the backup, the less chances for problems.
Is this a known problem?:
That depends on what you consider known...I have helped people on forums simply by telling then to not use there iOS 4 backup...only to find out it actually helped them. I have no idea if it is a "known problem". I just know it has gotten users out of jams with there iDevice. That is all I know.
To me, in my honest opinion.....this is a "known issue".
Why wouldn't it be caveated with iTunes?:
You already asked this question when you asked if iTunes should show a warning. Same question....different words.
I have no idea.
iTunes has a lot of actual "known issues" that are not forewarned at all.
They do not warn you that transferring purchases can mix up all your album art. They do not warn you that when you sync apps...that some apps just won't sync to your device for almost no apparent reason. They do not warn you saying that some of your music may gray out and not be able to sync to anything at all, even tho you can play them fine in iTunes. Those are just a few "know issues" I an think of that iTunes does not warn you about at all.
