Joe Rossignol, writing for MacRumors: ModMy last week announced it has archived its default ModMyi repository on Cydia, which is essentially an alternative App Store for downloading apps, themes, tweaks, and other files on jailbroken iPhone, iPad, and iPod touch devices. ZodTTD/MacCiti also shut down this month, meaning that two out of three of Cydia's major default repositories are no longer active as of this month. ModMy recommends developers in the jailbreaking community use the BigBoss repository, which is one of the last major Cydia sources that remains functional. The closure of two major Cydia repositories is arguably the result of a declining interest in jailbreaking, which provides root filesystem access and allows users to modify iOS and install unapproved apps on an iPhone, iPad, or iPod touch. When the iPhone and iPod touch were first released in 2007, jailbreaking quickly grew in popularity for both fun and practical reasons. Before the App Store, for example, it allowed users to install apps and games. Jailbreaking was even useful for something as simple as setting a wallpaper, not possible on early iOS versions.
