Install i OS 7.0.4 update via i Tunes Some folks prefer to physically connect their i Phone to a computer via a USB cable and update their phone via i Tunes.Since you are not dealing with Wi FI signal, there is less chance of an error occurring during the download and install process. take a moment to make sure you are using the latest version of i Tunes.You may also want to connect your i Phone to your local Wi Fi network, so you don’t get charged for downloading the update over your cellular connection. i OS will automatically check for available updates and will inform you that i OS 7.0.4 software update is available. Wait for the download to complete and then tap Install to apply the update.If you get tired of waiting for the download to finish (it could take a while) then go do something else.Other than the cost, there's really no reason to continue to use an i Phone 4 at this point. That gives you the best of both worlds: you'll get a fresh, fast new phone with all the latest hardware features and the latest version of the i OS.I'd much rather pay a few hundred dollars for all those new things than having a poor experience on an old phone.Your i Phone or i Pad will continue to download the update and will send you a notification when the update is ready.
