Where do I get the latest radio update for T-Mobile and the steps to it?

the latest firmware is not really required for any of the ARHD releases. But if you really want to I get them from here >> HTC1Guru - HTC One Stuff

Theirs instructions and they include radios. You should backup your current radio before updating just in case.

adb shell
dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img

You will now have current Radio on SD as radio_firmware.img
In case you want / need to restore your current Radio backup:

Either you adjust updater script to radio_recovery.img or just do it via adb in recovery:

dd if=/sdcard/radio_firmware.img of=/dev/block/mmcblk0p31
