Guys, Can someone tell me if on iPhones, the 4G toggle switch is shown ONLY IF 4G is supported by the network? lets say that the phone is used on a network which has 4G but is not enabled by Apple? will it show the 4G toggle switch? I live in Sri Lanka and im on dialog telekom which is a 4G network but the iphones are not supported for 4G in sri lanka, today i got a carrier update thru itunes and now i see a 4G switch instead of the 3G switch and the carrier is updated to Dialog in the about page. I cant check 4G yet because i need to get a separate sim for the 4G and right now im @ work so dont have time to go out. Can anyone confirm this?
