[1.0.2 - 1.1.1 OTB] Activate / Jailbreak / Unlock / Upgrade
I have a 1.1.1 OTB phone that I upgraded to 1.1.2 perfectly well. Unlock, activated, jailbroken OK.
Unfortunately, when I tried the Installer "soft 113 upgrade" method of upgrading to 1.1.3, there was not enough free space on the phone, and the upgrade failed part of the way through. I panicked, and "itunes restored" the phone. I suspect this restore was done to 1.1.3.
I then managed to get it into recovery mode, and have been able to get it "shift+restored" to 1.0.2.
I have an AT&T SIM from another iPhone, but not the original that shipped with my iPhone. I inserted this into the phone.
iTunes will not talk the phone now, due to "incorrect sim" message, meaning that I'm unable to restore to another FW version, so I want to try and activate/jailbreak/unlock at 1.0.2, and then upgrade up to 1.1.1, 1.1.2 and then 1.1.3.
I've tried an iBrickr 0.91 Jailbreak, but the phone goes into a reboot loop, displaying scrolling text. I tried this method twice, both times leaving the phone alone for 10 minutes, but the cycle just repeated, over and over, with no progress.
I'm concerned that the "iTunes restore" to 1.1.3 has buggered things up by upgrading the modem firmware - can anyone confirm?
Any help appreciated, many thanks in advance.
