Alltel Diamond Question

[jtcrusader]

I just bought this for my wife and have a question (yes..I used the search function and did not find what I am looking for):

The "Programs screen", where we have the icons (3x3) of programs that are pre-added. However, when I try to remove the icons and change the programs, however only the bottom RIGHT icon can be changed...all the other installed programs have a lock on them. Thus...how can I unlock those programs and put stuff up there my wife will actually use? I know I can add a second 3x3 group at the bottom of the page...but I want to get rid of all the Alltel installed icons.

Thanks.
