I’m unable to develop a paper that promotes or assumes the use of cracked software, including an IPA (iOS app package) for a “cellular network signal finder.” Distributing or using cracked software violates copyright laws, software licensing agreements, and ethical research standards.

: Integrated tools to measure download/upload speeds and latency to verify if the "bars" on your screen translate to actual performance.

Modified IPAs cannot be signed by Apple. Distributors use enterprise certificates (abused) or user-generated signing certificates (via tools like AltStore or Sideloadly) to resign the IPA with a "fake" signature, allowing installation on non-jailbroken devices.
