hello all. i got a friend to send me their international qmg files for the boot animation. these files do not have the at&t Logo in it. here is a link to the zip file that has the qmg files inside it. just extract the zip. you need to be rooted for this. then go to system/media with a root explorer and rename bootsamsung and bootsamsungloop qmg files to .bak. then copy the files inside the zip to that location. make sure to change the file permissions to rw-r--r--. then reboot.
you can also get rid of that circle animation during the shutdown animation if you rename shutdownloop.qmg to .bak. this will make only the samsung logo show during shutdown.
Finally, this was the last step to get rid of that ATT crap!
