The Fuze is actually a P4600. I fixed the phone mis-identifying itself by editing the DEVICE_CUSTOMIZED_0_0_0_0 provmxl files. I edited any section that referred to a T7272 so that it read the same as what was in the ATT provmxl files. The phone correctly ID's itself now but I will have to go back and look deeper into this issue, because I still can't buy things from the ATT wap store (says my phone isn't supported, so there is some other settings I need to find).
The issue with the icons was fixed by not including the ResourceUpdates package. Later when I have more time i'll try to figure out what file specifically in this folder is changing the icons.
I was unable to figure out how to change the fonts, as there is no registry entry for these programs that changes the font, and there was nothing in the provmxl files for that either. I don't have the knowledge/tools for editing .exe or .dll files so I may have to settle until I can figure this out.
