mobile

i have the att variant of the edge and it has various screens for different settings. ive seen people post over the internet about how much they hate it, but with no way to have the single vertical layout. i assumed all was lost until my manager whips out her 64gb gold s6 with t-mobile and asks me to help her set it up. does anybody know if the settings menu is carrier dependent or if it can be changed? please and thanks...
