So the 1.1.4 Firmware was out for a while now, and many have upgraded to it without any real issue, so I decided to take the plunge and do it myself. I was on 1.1.2 prior to this upgrade and since I had no problems with it, I kept delaying the upgrades.

1.1.4 has a few neat features, like rearranging the icons, and locating yourself via cell triangulation on a Google Map, but that’s all there is to it. The main reason for my upgrade was that new software is built for 1.1.4 mainly, and I wanted to be able to try them and use them.

The upgrade went fine thanks to the fine folks at the iPhone Dev team, Aviegas and Geohotz who all contributed to this solution. I used iPlus 2.0b which takes the freshly restored iPhone on 1.1.4 firmware, jailbreaks it, unlocks it, and does it all with no harm to the iPhone itself. The process is completely reversible, which make it a friendly solution should a hardware damage occur and I have to take the phone back to Apple.

Here is a screenshot of the About screen on my iPhone, you can see its on the 1.1.4 firmware.

The upgrade like I said went fine, the only thing i needed to make sure is that I don’t lose my SMS’s, contacts and Browser History, call history.

For keeping SMS, Call History and Browser History/bookmarks, I had to copy the following files off the iPhone, and then back again once I was done with the upgrade. You will see the paths are different, and that is because some folder structure changed starting with 1.1.3 and on.

[code]
/var/root/Library/CallHistory/call_history.db - /var/mobile/Library/CallHistory/call_history.db

/var/root/Library/Safari/*.plist - /var/mobile/Library/Safari/*.plist

/var/root/Library/SMS/sms.db - /var/mobile/Library/SMS/sms.db
[/code]

Other than this, I had Lockbox which I needed to keep, and it had 2 .db files. One for the data and one for the settings. Again, I just copied these db files off the iPhone, and back after the upgrade, things are working great.

And finally contacts, I use iTunes sync to Outlook, so all my info, calendar entries, tasks were back on in a matter of seconds.

Here you can see some pictures I took on the way of upgrading, and finally the home-screen with the wiggly icons. The icons wiggle when you manipulate their positions. Its the main new feature in 1.1.3/4.

Cheers
