Here is the list of all iOS versions that Apple released since 2007 with the introduction of iPhone. Below you will find version number mentioned with its release date and signing status.
What is signing status ?

All iOS softwares or firmwares that Apple releases over iTunes have their signing status. All firmwares passes through Apple servers during software restore or update. if a firmware's signing window is closed that means Apple doesn't support the firmware to be restored on an iOS device. This whole firmware expiration started with the release of iPhoneOS 3.0 in 2009. Below we list down all the versions that Apple is still signing on their servers. To simplify our firmware links doc, we are removing release dates of iOS versions from that doc including signing status and gathering all that information in this new document. This doc is only created for information purposes only. Read this doc if you are interested in knowing release dates or Apple's signing status.
