Manila Customizer?

[igotgame]

Will it work on an Alltel phone with stock rom?

I tried changing the clock on my phone, but it just turned TF3D off and made my today screen blank....I restored my old settings back and restarted TF3D and everything is back to normal, but is there something I need to do once I try and install a clock? Do I need to turn TF3D back on after setting the clock I want or soft reset?

I was worried about trying again because of it basically making my phone look blank when I tried last time. Just curious if I am missing something here and if this can be done on stock roms?

Thanks in advance
