JailbreakMe included Cydia, a package management interface that serves as an alternative to the App Store.

[5] The team estimated that 100,000 devices were jailbroken in the first three days of its release, growing past 1 million in the first month.

[3][6] JailbreakMe 2.0 "Star", released by comex on August 1, 2010, exploited a vulnerability in the FreeType library used while rendering PDF files.

[10][11] Comex also released a patch for this FreeType flaw, named PDF Patcher 2, which is available as a free package installable via Cydia.

After tapping "INSTALL", Safari would close, Cydia would load as a new app, and the device would be jailbroken with no reboot necessary.

Whilst technically semi-untethered, the jailbreak could be made fully untethered with the use of tihmstar's UntetherHomeDepot package.

TotallyNotSpyware, created by the JakeBlair420 team, released on September 7, 2018, is a JailbreakMe-style exploit that works on any 64-bit device running iOS 10.
