GO SMS iPhone (iOS) Theme GO SMS iPhone (iOS) Theme
the author of this app says:
The best and more accurate GO SMS Pro iPhone theme on the android market, with all the buttons and conversation bubbles like the original. A perfect match for your GO Launcher EX iPhone theme.
***Remember***: this is a GO SMS Pro theme, so you need GO SMS Pro installed on your phone (it's free). Then you can select the theme called "Iphone (iOS) Theme" from the GO SMS Pro Theme settings, it will be the last theme down on the list.
If you want the support for the Iphone emoji you simply need to install the GO SMS emoji plugin (it's free).
