iPhone Firmware 1.1.3 Now Available, Lots of New Features

As was widely predicted, iPhone firmware 1.1.3 was released today after the 2008 Macworld Expo and is now available for update via iTunes or via direct download. Most of the predictions about what new features would be coming with with 1.1.3 were dead on, mostly due to the fact that a version of the iPhone 1.1.3 firmware was leaked ahead of release.

Where are iPhone firmware files stored on my computer?

Apple doesn't go out of it's way to tell you where iTunes stores the firmware files it downloads before it updates your iPhone. Should you ever need to access these files, it helps to know where to find them.

Firmware files have an .ipsw extension and can be found at the following locations:

On Windows XP :
Documents and Settings\<User>\Application Data\Apple Computer\iTunes\iPhone Software Updates

On Windows Vista/Windows 7:
Users\<User>\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates

On Mac:

iPhone Firmware 1.1.2 Available

Last night, iPhone firmware version 1.1.2 became available. Though available for download here, the firmware is still not available via the iTunes auto-update feature.

Clearly it is only a matter of time, likely within the next few hours, before 1.1.2 is fully integrated with iTunes.

Hackers Regain Access to iPhone Under Firmware 1.1.1

Erica Sadun of TUAW, well known in the iPhone community for "Erica's utilities", has been liveblogging her attempt to replicate the success of two iPhone hackers, named "dinopio" and "Edgan", who have recently regained access to the full file tree of the iPhone through a bit of upgrade trickery. The latest update show that Erica has acheived similar success, proven by screen shots she has posted.

Evidently, access was regained by symbolically linking (symlinking) a portion of the iPhone's filesystem prior to an upgrade from firmware version 1.0.2 to version 1.1.1. The symlink in question is created by backing up the phone's Media directory and then symlinking the filesystem root to the Media directory.

Once the symlink is in place and the iPhone is upgraded, access is gained to the entire file tree using iPHUC (the iPhone Utility Client). In Sadun's tests, read and write access is tested and working, and a copy of the new Mobile Music Store application (MobileStore.app) has been pulled down.

The hope is that this latest development will give hackers the access they need to once again re-open the
