iPhone 1.1.3 firmware behind the scenes changes

So I've had the chance to examine the 1.1.3 firmware on a deeper level (using a technique not developed by me and which I can't release so don't ask) and have noticed some interesting changes behind the scenes that are quite blogworthy:

- SpringBoard no longer needs to be modified (via SummerBoard) in order to show extra applications in the /Applications folder.
- All applications now run as the user 'mobile' instead of as root.
- Preferences are now stored in /var/mobile rather than in /var/root.

What does this all mean? I'll tell you what it means.

The iPhone 1.1.3 firmware is ready for official installable applications.

Even though there are no applications available for purchase (besides the iPod Touch's $20 "upgrade package"), the installation architecture appears to be there already.

It also appears that the frameworks have undergone many changes, ostensibly to make it easier for official SDK developers to make programs. It does, however, break many of the existing applications including most of mine (Lights Off still works though :D).

Additionally, the SpringBoard app appears to have widget support - it contains a class called SBWidgetApplication which manages the package location and icon.

I will update this post with more details as I find them, so keep checking back.

Also check out this other hack for adding Speed Dial icons to your 1.1.3 home screen.

** iPod -- Hiding a sandbox outside of a honeypot?
** Please have your credentials ready for launchd
** Ah. I see your papers are in order. Welcome to Interzone, Mr. IP*owned!

<rdar://problem/5254675> Merge embedded changes into TOT
<rdar://problem/5692704> SpringBoard needs custom launchd job management API

Seriously, it shows some security maturity on Apple's part to release this code under Apache 2.0. I would not wish to install an application on my iPod alongside a mechanism for paying for applications unless the implementation was solid.

* Much of the wonder questions about why two-stage dynamic libraries are appearing at fixed addresses appear to be cleared up by this post.

* would not be surprised if the entire OS that was 'jailbroke' was not a big 'honeypot'

* Has anyone set ahead their computer clock to see if their are any iPoison capsules slowly disolving?

* I have read that the iPod itself checks to see if its date is manually updated... and this arm arch supports an internal clock kept seperate from the 'realtime' clock just to detect induced clock skew...
