Just wondering how they can manage to produce something that will only run on this phone?
- tlrobinson 11y agoEasy. Since iOS software must be signed by Apple they could simply hard code a check for a specific device ID, and immediately exit if it doesn't match. Then they sign that specific binary.

- EdHominem 11y agoThat isn't really easy. 99% of the phone can be tampered with when running, after the signature is checked at install. They'd need to put that check in the secure enclave to make sure that it wasn't simply bypassed. That might not even be possible on that model.
