The OTB iPhones with 1.1.2 pre-installed are posing some serious issues as far as unlocking them are concerned. That won’t stop you guys from using the iPhone without a contract (Cingular / ATT). Yeah, you can Activate and Jailbreak your iPhone which makes them usable with ATT and Cingular sims without a contract. Just follow my post which involves downgrading to 1.1.1, followed by OktoPrep 1.1.2 and then Upgrading to 1.1.2 and Jailbreaking/Activating it (All the features except for Phone can be used with other sims).

The bootloader (4.6) on OTB 1.1.2 iPhones is tough to crack which should be announced very soon iPhoneDevs always succeeded and so does our hopes! Keep an eye on this post for 1.1.2 OTB unlock!
