iPhone 3GS End of Life Date
iPhone 3GS end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
iPhone 3gs was released on June 19, 2009 and support ended on February 21, 2014 — a supported lifespan of 4 years and 8 months, shorter than the 7 years and 7 months median for iPhone releases. It has been without security patches for 12 years and 6 months. 44 newer iPhone releases have shipped since.
What does iPhone 3GS end of life mean?
When iPhone 3GS 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 3GS 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.
