When I turn on my Galaxy S2, on the very bottom, there are the default icons for "phone", "email", "web", and "applications". On the Galaxy Tab (running Android 3.2), if I want to free up any of those apps and replace them with my own, I simply press and hold like any other app and just delete and replace with my own.
On the Galaxy SII Skyrocket (running 2.3 Gingerbread), I press and hold and nothing happens. Is there a way for me to change the shortcuts in the dock on the SGSII, similar to the way I can on the Galaxy Tab?
