after stuffing myself with turkey and pumpkin pie, i opened the newly delivered iphones from the online apple store – lo and behold, it’s an otb 1.1.2! yey! now i’ll have a chance to play with this new firmware. after countless servings of mini muffins, i finally saw the light.

here’s a guide on how to unlock an otb 1.1.2

what you need:
1. otb 1.1.2 iphone, week 46 and up for us.
2. iphone 1.1.1 restore file (the old one, the one from apple site has tiff patch so you wont be able to use the old method to jailbreak and activate)
3. iphone 1.1.2 restore file (just download from itunes)
4. ibrickr 0.9.1
5. jailbreak 1.1.2
6. patched lockdownd file
7. winscp or any ftp client of choice

steps: (this is not detailed and idiot proof)
1. restore to 1.1.1 using itunes
2. get out of dfu mode through ibrickr
3. jailbreak and activate, follow up to step 7
4. from installer.app, install oktoprep.
5. update to 1.1.2 through itunes
6. jailbreak and activate using jailbreak 1.1.2
7. from installer.app, install openssh
8. connect to your iphone using winscp and backup /usr/libexec/lockdownd to your pc
7. upload the patched lockdownd to the same location.
8. insert sim of choice, reboot.
9. done!
