So just got home with my phone and was shocked to find that iCloud had backed up EVERYTHING from my iPhone 4 and placed it onto my 5, down to my SMS messages. That was the biggest kick in the ass upgrading from the 3G.
I fully expected to lose a ton of stuff even with an iCloud backup, but NEWP.
This feature may have just sold me on iPhones for life.
Yeah, iCloud backup/restore has been a great improvement.
