Answer to "iPhone 4S keep searching for network after replacing battery"Easiest way to do. Use your friends iphone, make a personal hotspot with it. join the wifi created by the other iphone and go reset the date and time by switchin it to manual and back to automatic and it will retrieve the info from your friends iphone network. After this restart phone. I tried my home WIFI and it wouldnt work with that because theres no info for apple available.
