iOS Updates - Apple® iPhone® 4S

This provides instructions for updating the software/iOS on your iPhone 4S. Our Troubleshooting Assistant can help you with other device issues if you aren't currently using the tool.

Note Notes:

  • The Apple iPhone 4S requires the latest approved software version. Installing other software versions (e.g. Beta versions, unapproved software versions, etc.) could cause issues with activation, apps and other device functionality.
  • To verify the iTunes software version, refer to iTunes: How to find which version you are using for assistance.
  • iOS updates can be either optional or automatic. The on screen prompts of the iOS download, backup and update may vary.

 

Caution Warnings:

  • If the device fails to reboot after performing the iOS update (e.g. device freezes/hangs), perform the reset method.
  • Performing the iOS update outside of the Verizon footprint could cause issues with voice and/or data resulting in diminished device functionality.
  • The iOS update process may takes several minutes. To avoid potential data costs it is recommended to connect to a Wi-Fi network.
  • Depending upon the iOS file size, the update may require being performed using the Wi-Fi or iTunes update method and not the Cellular Data update method.
  • If unable to perform the over-the-air (OTA) iOS update due to insufficient memory available on the device, perform the iOS update using the iTunes method or remove files on the device that are no longer needed to free up available device memory.
