How-To: Determine Apple iPhone LCD Version

How can you tell if you Apple iPhone has a series 5 or a series 7 LCD screen? Unfortunately, you cannot tell without opening the box and activating your Apple iPhone. Thankfully though, it doesn't take a brain surgeon or technical genius to figure it out. Determining the LCD version of your Apple iPhone is as simple as dialing *3001#12345#* and tapping the "call" button (that's *3001#12345#* - it starts and ends with an asterisk.)
