How to Delete iPhone Memory

The Apple iPhone can store up to 32 GB of multimedia, applications and more, depending on the model. There may come a time when you want to delete your iPhone's memory, such as if you plan to sell it or if you want to alleviate technical errors. The iPhone does not have built-in tools to clear device data on its own. Instead, you must use iTunes to set up the memory deletion.

Step

Load iTunes and connect the iPhone to your computer using the iPhone's USB cable.

Step

Select your iPhone from the iTunes "Source" list on the left. Basic iTunes functions appear in the main panel.

Step

Click "Restore." A dialog box pops up asking you to back up the iPhone or skip the action.

Step

Choose "Back up" if you want to save all of the data on your iPhone to iTunes before deleting the iPhone's memory or choose "Don't back up" to skip the action.

Step

Click "Restore." iTunes deletes your iPhone's memory.
