Updating to 4.2 using the AT&T ROM

[randydparsons]

Is it possible to update my I747m to 4.2 from 4.1.1 using the AT&T 4.2 ROM >WITHOUT< rooting my phone? I had issues when rooting last time and had to delete all my data recently, which was not a good time.

Thanks for your replies!

No because Samsung nor AT&T has released 4.2 for the S3. For that matter no S3 has an Official S3 4.2 rom. The latest rom is 4.1.2.
