People coming from the AT&T 13.37 radio do not have issues. You may need to upgrade 1st. People using the Non-AT&T versions won't be able to flash this. You have been warned!!! FLASH WORTH RECOVERY BEFORE YOU FLASH THE ROM! 76XXC-63805040-SDCBALUM
This next one is for non-AT&T users. Confirmed safe for VIVO, Oi, TIM, Personal Móvil Argentina & Telcel. Nobody has reported loss of 3G functionality yet, but possible. You must flash this in recovery. This must be flashed BEFORE YOU FLASH THE ROM! I do not know what 3G bands this radio.img uses. When I find out it will be posted You have been warned up front! Do your research first! If this causes you to lose 3G I am not to blame. There is also the possibility that you won't be able to downgrade! You made the choice to flash this not me! Thanks to @mugedy for making the update.zip for people to test! signed-IT_radio.zip
