iPod/iPhone firmware .ipsw files (can be deleted)

(This post will likely not interest most of my friends and contacts - it is here more as a reference in case somebody out there is looking for this information and Google has indexed this page...)


The iPod firmware files, usually located in the /%Username%/Library/iTunes/iPod Software Updates and named, e.g., "iPod1,1_3.0_7A341_Restore.ipsw", may take some HDD space. They are around 250MB in size.

I have found on my Mac mini the following ones, giving actually a good idea on how the size of the firmware has changed through the various versions. From OS 1.x to OS 2.x there was quite a jump, but OS 3.0 is actually smaller than the latest OS 2.2.1.
Here the details:

iPod1,1_1.1.4_4A102_Restore, 165.5MB, March 2008

iPod1,1_2.0.1_5B108_Restore, 246.7MB, August 2008

iPod1,1_2.0.2_5C1_Restore, 246.2MB, August 2008

iPod1,1_2.1_5F137_Restore, 239.5MB, September 2008

iPod1,1_2.2_5G77_Restore, 248.1MB, November 2008

iPod1,1_2.2.1_5H11_Restore, 248.1MB, January 2009

iPod1,1_3.0_7A341_Restore, 231.2MB, June 2009


The date is when the update was done - in my case is typically 1-2 weeks after the firmware was released, so they should be pretty accurate.


According to this post in the Apple forums, it is safe to delete all files to recover disk space.
