I don’t see a compelling reason to do this, but it’s good to know that you can without bricking the phone. 1.1.2 doesn’t add any killer features, and seems to only patch the .tiff vunlerability (which, if you’ve followed the normal process, is already fixed). But, as an exercise so you don’t have to, I’ve upgraded my iPhone to 1.1.2 to see how it goes.

Here’s how you get from 1.1.1 to 1.1.2 without having to go through and reinstall all your music. As usual, no guarantees, smoke & flame, backup your data, and your mods will go away, etc etc, but this worked for me:

1. (you know it’s coming) sync your data & download your pictures.

2. Not really a step but, remember, you might your voicemail and email passwords to enter after the upgrade. So get those ready. (I didn’t need them but doesn’t hurt to check)

3. Go into the installer.app and select “oktoprep” from “recent packages”. You’ll get a popup window on the iPhone/iPod touch saying “You are now ready to perform an “Update” to 1.1.2 and continue with the TouchFree process.” Now, it doesn’t tell you or me what the “TouchFree process” is, or how we are continuing with something we didn’t know we were using, but lets read on together and find out.

4. Click “Update” in iTunes. Hmmm. “This version (1.1.1) is the current version.” What’s up with that? Turns out Apple hasn’t pushed it yet but it’s on their download site: http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-4037.20071107.5Bghn/iPhone1,1_1.1.2_3B48b_Restore.ipsw

5. Click on that URL and when your browser asks you what to do, save it to disk somewhere you can find it in step 7.

6. Wait patiently for the download to complete.

7. in iTunes, hold the shift-key while clicking on “check for updates”. It’ll open up a finder window asking you which file to use. Select the file you just downloaded (iPhone1,1_1.1.2_3B48b_Restore.ipsw) from where you just saved it to.

8. “Extracting software”

9. “Preparing iPhone for software update…”

“Waiting for iphone”

“updating iPhone software” (phone goes to silver-apple screen)

“Verifying updated iPhone software” - this step takes a couple minutes, phone screen still showing silver apple.

“Updating iPhone firmware”

“Your iPhone has been updated”

Phone reboots. My pictures are still there, because it just asked to download ‘em again to the OS.

“Waiting for activation”

“iPhone is activated”

“Slide to unlock”

OK, so, there’s the stock screen with the standard 17 icons. Pictures are there. No music but I didn’t have any music on it before so hard to say. But, I’ve shown I can get from 1.1.1 hacked to 1.1.2 without problem, in case you feel some compelling reason to move that way.
