Is the iPhone 5g different from the iPhone 5?

there is not iPhone5g

there is an iphone5s which is the latest model and an iphone 5c - the 5c is basically an upgraded version of the 5 in plastic and comes in several bright colors

the 5s is the highend new iPhone - faster processor- motion coprocessort- fingerprint sensor

if you go to the Iphone page at

www.apple.com you should see a comparison of the various iPhone models currently offered which are the 5s, 5c and 4a

you can also say nah g is generation of the phone network

then

phone was 1-1/2(Edge)g

Iphone 3 was 3g

Iphone 3s was 3g

Iphone 4 was 3g

Iphone 4s was 3g

Iphone 5 was 4(LTE)g

Iphone 5s and c would be 4(LTE)g

in which case the iphone5g would be an non existing device for an nonexisting cellular network

What is a 5G not seen that at Apple Store

G is generation

So

Iphone was 1g

Iphone 3 was 2g

Iphone 3s was 3g

Iphone 4 was 4g

Iphone 4s was 5g

Iphone 5 was 6g

Iphone 5s and c would be 7g

Now that is lateral thinking 😉
