The app, like all apps, will only use cellular (2G, 3G, 4G) if you are not connected to Wi-Fi. You will connect to Wi-Fi automatically if you are in range of any remembered networks you have already manually connected to at least once.

iPhone 3G S = iPhone 3G + Extra's
It was an iPhone 3G

Apple invented the iPhone 3G.
Both the iPhone 3G and the iPhone 3G S support MMS with the 3.0 update.
iPhone 3g is capable of 3g access, but not iPhone 1st generation. However, some areas do not have 3g coverage, so iPhone will automatically switch to EDGE. iPhone 1st generation only has EDGE and Wifi, and iPhone 3g has EDGE, 3g, and WIFI.
Definatly the IPHONE 3G!!!
No, the iPhone 3G does not have a front camera.
2g is 2nd generation 3g is 3rd generation. 3g is much faster. iPhone 3G can support WCDMA and HSDPA frequencies, but the iPhone can't.
The iPhone 2G is much slower than the iPhone 3G.
You can technically install Instagram on an iPhone 3G, but the app may not function properly due to hardware and software limitations. Instagram requires iOS 10 or later, while the iPhone 3G can only run up to iOS 4.2.1. Therefore, it's unlikely that you will be able to use Instagram effectively on an iPhone 3G. It is recommended to use a more modern device for the best experience.
