I have an Att S3, with Jellybean 4.3. I see Perso SHA256 OFF but afterward the ( NW Lock NV Data INITIALLIZ) option does not appear. The only options that appear after I click on Perso SHA256 OFF, wait 30 seconds and hit back button are....
NETWORK LOCK  PERSO SHA256 Info  PERSO SHA256 ON  PERSO SHA256 OFF  RAT_FREE_SUPPORITNG ON
Are the steps different for the Jellybean 4.3 version? Has anyone had any luck with this?
This method only works if your phone is running a older version of the android software. If you are running a newer version the menu to access these settings are gone and you will need to downgrade your device to a lower software version in order to get the options to do the free unlock trick and for some CDMA phones after you do this and reboot the phone the unlock gets reverted back to locked status and you will need to redo the settings again to get it working again. If you guys are scared that you might screw up your phones and don't want get all worked up then you can just simply buy a code that you just type into the phone for a few dollars and save yourself the headache. I used this site from time to time and they have days where you can get some codes for free. They actually have unlocks for for all major carrier GSM and CDMA phones and all you need to do is to just enter the unique numbers to get your permanent unlock codes. If you end up getting blacklisted phones from the Bay or CL they also offer a service to get those unlocked too which is pretty cool.

The OP stated on GSM, so I'm guessing no on the CDMA versions like Sprint and Verizon...
I believe most of the answers to questions ppl have are on xda...
Also, the seller on eBay with listing 321033698090 almost looks like a college student selling stolen goods? I could be wrong, but since he's selling stolen goods from xda...

I've noticed some newer Spring phones come with a slot for a SIM card. Normally, you can't unlock a CDMA phone, like Sprint or Verizon, the way you can with a phone that uses a SIM card, as all GSM phones (AT&T, TMobile, MetroPCS) do. Could it be that the newer Sprint phones are also GSM-capable, and might work with a foreign SIM card? I've noticed some phones coming out of China that are unlocked for GSM but also are said to be CDMA capable.
Maybe you can just put a foreign SIM card in the Sprint phone. See it it works, or maybe it will if unlocked.
