After some 40,000 users lost phone service and had their Touch ID disabled by a glitch in a version of the highly touted iOS 8 mobile operating system recently rolled out by Apple, the company appears to have quickly patched it up.

Available for download in iTunes, iOS 8.0.2 improves on the faulty iOS 8.0.1., which was discovered Thursday just an hour after the initial update was released and prompted Apple to let users restore the original iOS 8 mobile operating system.

Soon after the users installed the update, they saw the “no service” box and it persisted after the phone was turned off and restarted.

Promising an update within a “few days,” it actually only took Apple about 24 hours to get the job done. On the support page, Apple’s message clarifies the situation: “iOS 8.0.2 is available now. It fixes the loss of cellular service and use of Touch ID that may have affected you if you have an iPhone 6 or iPhone 6 Plus and you downloaded iOS 8.0.1. It includes improvements and bug fixes originally in iOS 8.0.1. We apologize for inconveniencing you if you were affected by the bug in iOS 8.0.1.”

Apple blogs have reported users were being notified about the update Friday and could go to their phone’s Settings button to install the software update.

The bug in iOS 8.0.1 apparently did not affect iPhone 4S, 5, 5S and 5C users, as Apple only mentioned iPhone 6 and iPhone 6 Plus on its support website, PC World’s Damon Poeter concluded.
