Before You Upgrade Your iPad or iPhone to iOS7, Read This!
Apple's newest operating system for the iPhone and iPad is out. And most of the features seem to work and most people will have no trouble upgrading. However, Apple does not give you an easy way to back out of the upgrade once complete. Here is a way to do it!
We learned this trick via having to replace an iPad under warranty. Following similar steps will allow you to "recover" back to your previous version and settings. A friend did not follow our advice and was on Apple's tech support for 2 hours. This is much easier.
First make sure you have iCloud turned on and do a backup using Wi-Fi by clicking "backup now". We have had others, including so called "Apple techs", say to back up to iTunes or backup to PC. We have tried this several times and never gotten a complete backup EXCEPT using iCloud and Wi-Fi.
Now after doing the backup TURN OFF iCloud backup. This is to prevent your new upgrade from writing over your previous backup.
Do the upgrade and test your apps and settings for a couple of days. As long as you do not install a lot of new apps or take a lot of new photos you should be safe. We did this for ~1 week and then turned on iCloud backup and did a "backup now".
Now IF you have problems here is how to restore back to your old system.
Go to settings General and Reset, "Reset all Settings". After several warnings and "are you really sures" this will set your device back to a factory setting. Setup the "new" device using the on-screen prompts. Then it will ask you if this is a new device or you want to restore a backup. Make sure you are connected to a Wi-Fi and restore from your iCloud backup. This may take an hour or more so have a charger handy.
We have used this restore procedure several times and always got back all our apps, photos, etc. Occasionally there may be a web site logon or password you will have to re-enter.
Good luck and enjoy iOS7!!
