Settings > iCloud. Make sure everything you want saved is on. Then make a back up. Proceed with a restore. Start the phone as new, log in with your Apple ID. It will then ask you if you want to restore from an iCloud back. It will likely list 2 entries with dates they were made. Use the one you just did and let it do its thing, the phone will (should) look identical to how it was when the back was made. The process takes a while downloading apps, photos, etc etc.Thank you and a quick question? Once I do this, will I loose any of my text messages?
