What is it?
* This is the RADIO pulled from the ATT Official UCMC1 Samsung Jellybean release. Note, this has no RIL (it appears the ril interface remains the same), but I have no idea if anything under the hood (device firmware) has changed. Also, no CSC. If you do NOT know what both the terms mean, search my friend.
* Don't ask will this work on X ROM. Read the stickies about RADIO's in the forum. You will find the answers. Or, for christ sake, search!!
* Check md5sum (download link has the md5sum)
* Usual flashing precautions should be taken.
* Choose zip from CWM.
