Now you need to wait until it is finished resetting your phone back to factory settings. Reboot your phone and it will be like a brand new phone, running more efficiently. Although this process will delete all your phone data storage, all of the contents on your SD card will not be affected, and left in tact. All of the Apps, pictures and videos that you've saved on your SD, will still appear on your Samsung Galaxy S3.

What does the icon look like for the internet?

The internet browser icon for Android devices looks like our planet earth. That icon is noticeable when you first held the phone, as it is present in the home screen. It also depends on the phone themes you have applied to the phone. There are a lot of themes that can be downloaded and installed on your phone to obtain a different look to your phone's applications appearance, but the default looks like the planet earth. Double check your phone's app drawer as it is present there

I do not have the option that says "Erase Everything" on my phone

When you tried to reset the phone by going to the Settings, if you are not seeing an option that says "Erase Everything" you should be able to see there an option that says "Delete All". They may look different but it is just the same as to erase everything on your phone's content. If you cannot find the "Delete All" or "Erase Everything", you can do a Hard Reset on your phone instead that is equivalent to the soft reset from the steps you are following. If you want to save the contents to a computer, just use the Samsung Kies to back up your data - then restore later. See the steps how to: Use the Volume keys later for you to highlight then the home button to select the one you highlight.
