Jailbreak (and fix) iPhone Firmware 1.1.3
I recently upgraded my 8 gig iPhone to the new 16 gig one, which unfortunately already came with the infamous 1.1.3 firmware. I spent quite some time looking for a guide on how to downgrade and this one by EffeXTC on ModMyiFone.com is by far THE best guide out there:
Yes, I used it and yes it worked. Before you start, make sure you have WiFi access. You’ll need it to jailbreak 1.1.1.
Some applications haven’t been modified to work on 1.1.3 yet, so you will have trouble with OpenSSH, Customize and SummerBoard. Oh, and Edge. Yea! No worries though. You can fix them.
Fixes for Jailbroken 1.1.3
Go to Settings -> General -> Reset -> Reset Network Settings.
Install Unix Subsystem and reinstall it. You might need to reinstall it a couple of times. You will NOT see the OpenSSH icon on your springboard but it will be running in the background. The username is root, and the password is alpine.
Add the following source to your Sources: http://sleepers.net/~iphone/repobeta.xml
Then, under Tweaks install Smb Themes Fix.
Fix MobileChat and Apollo
Go to Installer -> Tweaks (1.1.3) -> IM Chat 1.1.3 Fix
I haven’t tried this, but here’s a guide on how to get Customize to work.
