Thanks for the headsup and a more informative answer 🙂
Dude, calm down. Labman was just kidding with you - plus, you really are putting zero effort into this. If you're so concerned with how "clogged up" the forum is, don't make redundant posts when you could just search here, or browse the fisrt 2 - 3 pages of the forum. Since you don't appear interested in learning how to fish yourself, though, here's some free salmon:
-5.1 is a tethered JB (I know, I still have it)
-Jailbreaking will not update your BB (as long as you don't restore with a firmware that's not "NO_BB" / custom prior to jailbreaking). I can verify this as I've run a custom IPSW w/ NO_BB and then jailbroken that firmware, all w. the 1.59.00 BB still on the phone.
-The firmware you'll need can be found on iClarified.com if you really want to run 5.1.1
-Personally, the JB tool I used is RedSn0w - try it.
-Listen to Braxton, there is no real need to move from 5.0.1 to 5.1.1 (or 5.1 for that matter)
I'm asuming your phone is an AT&T phone... Are you elligible for an unlock now, or are you still under contract? A factory unlock would be better than a NO_BB IPSW as you won't have the "one signal bar" cosmetic side effect.
Enjoy your fish, sir
