iPhone 4 End of Life Date
iPhone 4 end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
iPhone 4 was released on June 24, 2010 and support ended on September 17, 2014 — a supported lifespan of 4 years and 3 months, shorter than the 7 years and 7 months median for iPhone releases. It has been without security patches for 11 years and 11 months. 44 newer iPhone releases have shipped since.
What does iPhone 4 end of life mean?
When iPhone 4 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running iPhone 4 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to iPhone 17e or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
