What will I lose if I DON'T restore from iCloud everything that was on my iPhone 4 to my new 5s?
I've just bought the 5s - have had a 4 since March 2011.
I've been told that there's the odd risk of bringing any bugs that may be on my 4 to my 5s if I "restore previous backup from iCloud" (or whatever it's called) when I turn on my 5s for the first time.
Things I'd like on my 5S that I have on my 4:
Apps, photos, music (though I have iTunes Match so not worried about this so much), notes, calendars (all on iCloud). That's about it I think, off the top of my head.
I'm not worried about having my texts from my 4 to my 5s as I'm not getting rid of the 4.
So four questions:
1. Are there risks of bringing bugs onto my 5s by restoring from iCloud backup?
2. What WILL port over if I set up the 5s as a new phone then just sign in to iCloud?
3. What will I NOT have on my 5s that I had on my 4 if I set the 5S up as a new phone?
4. If I set the 5S up as a new phone then decide I do want whatever is on the 4 can I "restore previous backup from iCloud" at a later date or is it a one chance only thing?
Thanks!
iPhone 5s, iOS 7.0.2
