Just sync your phone with your computer. Then using your computer go into your phone's program file>S2U2 directory. Copy lang.ini to your computer and open it with notepad. In there you can change any text you want S2U2 to say. Then just copy that file back to your the S2U2 directory and overwrite the existing lang.ini file on your phone.
I just did this and it works just fine. Also make sure you open your S2U2 settings and save it. For some reason it would not update until I did this. Or a simple reboot might do it as well.
I hope this helps
