I have a 4s with ios 6.0 and have a 9G backup in the cloud. I "drowned" my phone while on vacation and bought a new 7 with ios 10. The problem is that the 7 is "unable to be restored because of a problem with backup data" I'm clearly not a technical person but thought the problem might be that there is too big of a version gap. The hope is that I can find a 4s with 6.0 and will be able to download the backup, update ios on the 4s, create a new backup and then be able to update the new phone. Apple store was not able to help. Anyone encounter a similar problem or have suggestions? Much appreciated.
