The demo person said I could plug my model number in on the website and find out if my phone is an iPhone 3, 4, 5, etc. , but I don’t see a place to do that.
Information can be found here on how to identify what iPhone you have: https://support.apple.com/en-au/HT201296 Alternatively, you can input the hardware serial number here to check as well: https://checkcoverage.apple.com/au/en/ You can find the serial number either at the back of the phone, on the sim card slot or in the phone settings itself. Usually - Settings > About iPhone / iPod / iPad / etc > Serial Number
