Maybe better try our Android forum: http://forums.cnet.com/android_forum/ for this question. This forum - but you didn't know that - is more about TV's and DVD-players than about Android software.
I am using galaxy y with touchwiz 3 installed. I am planning to install go launcher ex. Do I have to uninstall touchwiz before that? Also if I want to go back to touchwiz later how will I do that? Will uninstalling go launcher suffice or I will have to do something else?
Thanks in advance.
