I got the version 3.1.2(7D11) with a modem firmware of 05.11.07, I'd really not like to brick the device. Do I run the iPhone1,2_4.2.1_8C148_Restore update via itunes, and then run redsn0w, etc..? I've just not seen info on what older models should do, I also do not have the original AT&T Sim only my tmobile one. Or should I just restore to to the 4.1 upgrade and use the older ultrasn0w... I'm so far behind I'd still like to be safe... Noobie here any help greatly appreciated.
