I'm new to android, and I can't seem to replace the default messaging app icon with Go SMS Pro. My brother has an android phone, and simple held down on the icon until it shook and removed it. This would not work on this phone. I also tried another tip I saw for droid phones, which also do not work on this phone. I'm stumped, so any help would be great. To clarify, I mean the icon on the app tray.
