Upgrading the iPhone to Firmware 1.1.1

If you unlocked your phone using iPhoneSimFree’s commercial unlock, stop reading. This post because it won’t help you.

As I mentioned, I had held out on upgrading my iPhone to the 1.1.1 firmware. Early this week, all the necessary components came together to allow an unlocked iPhone 1.0.2 running third-party applications to be upgraded to firmware 1.1.1. The process is a little time consuming but it works. Not all of the third-party apps I was running have been upgraded to work on firmware 1.1.1 but most of them work quite well. A suggestion, before starting any of the upgrade processes, remove ALL of your third-party apps except the Term-vt100 and OpenSSH apps (you will want this as a backup for the upgrade process in case you can’t ssh into your iPhone). You may not be able to remove the BSD Subsystem because, Term-vt100 and OpenSSH need it. You will have to upgrade these manually after the upgrade to 1.1.1 because the Install App packages haven’t been properly updated.

Use the best guide to upgrading from an iPhone that was unlocked using anySIM or iUnlock.

FYI, after upgrading, I have less than 30MB free when using the Installer app. Under 1.0.2 I had around 90MB free. I’m not sure if this is dead space because I didn’t uninstall apps prior to the upgrade or the available space shrunk because Apple used it.
