If you have an iPhone 4s, there are a few ways to reset it without having to use iTunes. Here are three methods:

  1. Reset the phone using the factory reset button. This will erase all your data and settings on the phone.
  2. Reset the phone using a computer or another device. This will restore your data and settings to their original condition.
  3. Reset the phone using a software update from Apple. This will update your firmware and fix any issues that may have been caused by the factory reset or resetting of the phone using other methods.
