Easier iPhone 1.1.3 software jailbreak

I ran into Pete, Josh, and Andy at The Office earlier today and found out that a software jailbreak/upgrade for iPhone firmware 1.1.3 has been released. I was on the modmyifone site yesterday, finally upgrading my 1.0.2 iPhone to 1.1.2 and hadn't seen anything so I went back there for a look.

It looks like two different solutions were released several days ago but those had issues (the location feature in Google Maps not working, etc.)

This morning, cash7c3f, who owns modmyifone, posted that they have a new software jailbreak method for 1.1.3 that you can run from Installer.app.

And, if your phone was unlocked at 1.1.2, it should retain its unlock after the upgrade. (My phone retained its unlock from 1.0.2 to 1.1.1 and 1.1.1 to 1.1.2).

To get it, you have to add the modmyifone repository to your Sources in Installer.app.

Once you've done that, you can see it under the System category.

I'm going to keep and eye on this but probably won't install it until I see some feedback on whether it breaks anything.

I'm really happy with 1.1.2 because I finally have caller ID again for UK numbers and that was my biggest complaint. (If you had numbers in your phone book in international format +44 0779 etc. under 1.0.2, caller ID would not work when people called you from the UK; the numbers would show up as 0779 etc.)

Update: More info on the 1.1.3 official jailbreak from ModiPhone. They also report "a contacts-related issue" with the method that should give you further pause before trying it out.
