A friend's Iphone 5s is defective and Verizon has sent an overnight replacement. Tomorrow I will go over to her home to assist her to restore the phone from her itunes backup. I am not sure what version of iOS7 it may have currently on it, and she only has spotty LTE service at her home as her main connection to the internet (she uses a Verizon Myfi). So i was hoping/wanting to make sure to update her to 7.0.4 at my house which has excellent Cable/wi-fi service, before I attempt the restore from backup process. I know the phone can do the OTA update, but I have found numerous times that the full 1GB+ update seems to work better for a "new restore". So I want to do the 1Gb+ update on my fast unlimited connection, so that the phone is "fresh" as possible. So my question is, Can i update the firmware to 7.0.4 on my MAC computer using itunes, with her sim card removed, and then restore the backup files from her PC computer to the phone later in the evening?
