I'm a little new to Samsung rooting, since I'm coming from a Rezound. My only experience was with a Verizon Samsung Galaxy Tab. That was a PAIN to root, and took me half a day to do.
Antways, obtaining root by this method, do you lose whatever data you had currently on your SGSIII from apps, to SMS? If so, how do you backup what you have? I know a work around to back up my SMS with Go SMS, just by turning airplane mode on, and it backs up to your SD card instead of the cloud.
Also, will OTA Root Keeper keep us good for the next OTA?
