SIMtrace2 has a serial debug interface. It requires a serial-over-audio-jack cable that sysmocom sells in their webshop.

The serial output looks like this:

I'd like to look at files from the iOS 16 filesystem. It's super easy, so easy that everybody except me seems to just know.

tl;dr: unzip the ipsw-file and double-click on the biggest dmg file to mount the iOS file system.

---

Unzip the ipsw:

$ unzip iPhone14,4_16.0_20A5339d_Restore.ipsw

Trying to convert a plist file to JSON but plutil is giving you a hard time?

I want the CellBroadcast as JSON:

plutil -extract CellBroadcast json -o - test.plist

That fails despite it should not:

test.plist: invalid object in plist for destination format
