| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [2] | No widespread evidence of hardware tampering at the manufacturing level. |
| Known vulnerabilities | Very common | [3] | The final OS version (iOS 6.1.6) has numerous documented, unpatched vulnerabilities. |
| Prior attacks | Very common | [4] | Susceptible to various jailbreaks and exploits over its lifetime. |
| Updatability | None | [5] | Support ended with iOS 6.1.6; no updates available since 2014. |

| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Partial | [6] | Supported basic protocols (e.g., POP/IMAP, Exchange) but lacked modern standards. |
| Communications | Encrypted with obselete encryption | [7] | Used older SSL/TLS versions and WEP/WPA Wi-Fi encryption by modern standards. |
| Storage | Encrypted with obselete encryption | [8] | The iPhone 3GS introduced hardware-based Data Protection when a passcode was set. However, it used AES-128 and older key derivation functions that are considered weak by modern standards (e.g., pre-iOS 4 security model). |

| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Basic | [9] | Supported basic passcode and simple restrictions. Lacked advanced management features. |
| Authentication | Basic | [10] | 4-digit numeric passcode was standard. No biometrics or strong multi-factor authentication. |
| Brute-force protection | Basic | [11] | Basic increasing time delays after failed passcode attempts. No sophisticated rate limiting. |
| Event logging | Partial logging | [12] | Limited system and diagnostic logs; not extensive security event logging. |
| Passwords | Default/Common/Easy to guess | [13] | Simple 4-digit passcode was default; no mandatory complexity or forced change after setup. |
