I bricked my iPhone attempting to upgrade from 1.1.2 to 1.1.3. Last night I tried iJailbreak Mobile twice, but I mysteriously dropped off my wifi at 93% and then 94%, and that wiped me out. So I used iJailbreak, but it requires the “Soft Upgrade” package from the Installer repo, which has since been removed, which left me with 300+ megabytes of trash littered all over my iPhone. So I ran the “Official 1.1.3 Installer” and it worked! But then it rebooted and gave me the dreaded “Your phone is damaged, please bring it back to Apple” nonsense.
Luckily, you can put your iPhone into restore mode – aka “dfu” mode – by holding down the home key and plugging it into your computer. I restored to 1.1.2, and then upgraded to 1.1.3. So I am on 1.1.3, and thankfully, my phone works, so that’s good. But I’m no longer jailbroken, and that really sucks.
Here’s hoping the SDK is not as lame as some fear it might be.
