With the thousands of different applications available for your Apple iPhone, it sometimes gets confusing as to which ones will work on your specific model. Some applications may work on the iPhone 3G, for instance, while others can only work properly on the iPhone 3GS. Knowing what iPhone generation you have is useful as well, not only to determine which apps should be installed in it, but also so you know which software updates to install and download.It's relatively easy to identify your Phone model and generation. Below are some simple steps, which you can follow to do this.
1. Use the settings menu on your Phone. On your iPhone, click on Settings, General, About, then Model. You will be able to see the particular Model number or generation of your iPhone here.
2. Check the color. This can help you determine which of the five generations of iPhones you own. If the back casing is Silver with a black plastic cover at the bottom, then you own an original Apple iPhone. If you have a curved plastic black or white casing, then you have a 3G or a 3GS. If the back is a flat glass construction you have either the iPhone 4 or 4s.
3. Study the casing or the body of your iPhone. The original has a metal casing while the 3G and 3GS have plastic casings. The Apple iPhone 4 and new iPhone 4s, on the other hand are made of strong, aluminosilicate glass (which is the same type of glass used in windshields of helicopters and trains). This material is said to be scratch proof and 20 times harder than plastic.
4. Look at the size of your Phone. This can also help you identify your model or generation. At 11.6mm thick, the original is thicker than the iPhone 4 and 4s, but thinner than the 3G or 3GS. The 3G and the 3Gs both measure 12.3mm thick (because of their curved bodies), while the iPhone 4 and 4s measures only 9.3mm thick.
5. Check for the placement of the serial number. The original serial number is etched at the back of the phone, while the 3G and the 3GS have their serial numbers on their SIM trays. In addition, you can also identify the 3G from the 3GS by its back cover. The 3GS has a brighter and shinier chrome etching of the Apple logo and "3GS" on the back.
6. Go through the features of your Apple iPhone. Each generation or model has its own special features. The 3GS, for instance, has a compass, voice control, a 3.0-megapixel camera with autofocus and video recording capabilities, which the iPhone 3G does not. The Apple iPhone 4, meanwhile, has a three-axis gyro, a proximity sensor and an accelerometer. The Apple 4s features Siri Personal Assistant Software that cannot be used on the iPhone 4. Download the proper applications and updates to your Apple iPhone by making sure that you know the model and generation of your phone first. Keep the tips listed above in mind when looking for iPhone apps, accessories and programs.
