Several times now I have flashed a ROM and it killed my 2G/3G toggle even though it's in the ROM. The first two times I rerooted to fix it, but a couple weeks ago it happened again and instead of doing that I just flashed the radio about 5 times in a row. It just happened again so I flashed my radio of choice three times without booting into android and it's working like a charm. However, I think I might be the only one that this happens to because the few times I have asked about it here have been absolutely fruitless.
