iOS Shared Cache Extraction

Having fallen off the iOS-exploration train due to completing my Masters and other commitments, I have finally climbed back aboard in pursuit of understanding the telephony stack.

Like most things in iOS that are used frequently, the vast majority of the frameworks and libraries used in the telephony stack reside in the DYLD shared cache located at /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7.

In this post I am going to explain how to go about extracting this cache file so that you can then work with each library individually.

Get The Cache

The first step in all of this is to copy the cache over to your local machine. I did this using a program called iExplorer, but you can just as easily do it over SSH. As a side note, you can connect to your iDevice using SSH over USB if you install a tool called iProxy.

App Store Oligopoly FAQ

Apple and the App Store desperately need regulation. The "why" is outlined below, and I'll briefly describe the "how" right now. There are two proposed solutions:

Apple is forced to allow competition in the form of alternative app stores. This would effectively be "GateKeeper for iOS" which would give developers an avenue to distribute their own apps from Safari as well, similar to how software is distributed on computers. Ideally a CA would emerge to distribute certificates for developers to use so that users could trust apps on a per-developer basis. This "GateKeeper" would have settings similar to those on macOS, with the default state being "Only allow apps from the App Store," and another option "Only allow apps from Trusted developers." It would obviously have a setting under Parental Controls as well.
The App Store becomes regulated by some government body, either by antitrust laws being passed or by direct oversight. Antitrust laws are what will lead to #1 anyway.

I take no credit for this post, just happened to have it saved in a document and thought I'd be doing an injustice by not sharing this information once I saw the original post was missing! All credit goes to the original author, and without further ado...

Student Loan Default: A Guide

I’ve been wanting to write this for a long time, and seeing that person be in $500,000 of debt and no one really helping him on r/studentloans, I felt it was time to summarize everything I’ve learned. While there is great information on this sub, it is not centralized. It requires some digging. I hope now to bring all of it to the surface.
