I have a 4S running 6.1.2 JB'd, but something appears to be corrupted with a few of the settings. I need to 'restore', but somehow continuing back to 6.1.2 where I can JB.

I thought of perhaps doing the 'Erase device content & settings,' but I'm not sure if this will work? I have read mixed reports that JB'd devices will go into a boot loop.

Any ideas?

Erase device content & settings, will put your phone into a useless state of needing to be DFU restored (because it's jailbroken).

You cannot restore to 6.1.2 or lower, you can only restore to 6.1.3.
 
Good idea on removing the tweaks. The issue is relating to my "carrier". I am with Straight Talk (AT&T MVNO) and my About>Carrier has always said something along the lines of AT&T 8.0 or something like that. As such, it would display 4G at the top when I'm on HSPA. Now it shows "Unavailable" and it shows 3G. But whatever the issue is, if keeps removing my carrier profiles. It's like something has gotten corrupted.

I've tried restoring network connections.
 
Remove mobilesubstrate from your packages in cydia. It'll erase all your tweaks. I'd do that before I restore to an un-jailbreakable firmware
 
Yes I tried ejecting the sim. When I put in another sim (TMo) I get carrier: Tmobile 14.0. Perhaps there's a way to force a carrier update?

Where are the 'mixed reports'? I've never seen/heard a case where 'Erase device content & setting' will NOT go into boot loop.

Maybe you should try a new sum card. Since it works with the T-mobie sim, I don't think your problem is JB related.

Actually, there are many reports that doing this with iOS5 (on a JB phone of course) will not kick it into a boot loop, it just fails and sends you into a regular reboot. I believe this was true when using the Absinthe family of jailbreaks.

I have never tested it myself.
 
Either way.. anybody got any ideas on my 'issue'? I don't know if it's the SIM card, but I can't get it replaced (the network has stopped issuing AT&T sims).

It just.. 'happened' one day, and now it fails to show "Carrier" info. I think its trying in the back end every now and again, because when I switch from WiFi to 3G (technically HSPA), the network settings get reset and I lose my APN settings.

I have, however, full operating signal.

I know it will happen, I'm just giving an instance where someone was saying it won't happen

Where does it say it will not happen? All i see is it will happen in that thread.

I've been here long enough and see countless of threads telling people NOT do "Erase setting/content" in iPhone and I am curious to know where MDTyKe see these 'mixed report'.

I meant that particular person said that it wouldn't happen and when someone is clueless and sees someone saying it won't happen, it makes them confused on who to believe

Why can't you just go and ask for a sim replacement? It is clearly a sim issue since you tried with another sim card and everything works.

Because Straighttalk isn't selling AT&T compatible SIMs any longer, I doubt they'd send you a replacement. You could try one of these vendors on Amazon who I assume are selling older (leftover) AT&T ST SIMs:

But before you do that I'd find a friend with an AT&T iPhone and try swapping SIMs with them as a test. That should help you see where the problem really is - your phone or your SIM.

Good luck!
