Apple yesterday released iOS 8.0.2, a replacement for the botched update that shipped the day before but crippled iPhone 6 and iPhone 6 Plus devices by knocking them off their mobile carriers.

The turn-around for 8.0.2 was notable for its speed: Less than 36 hours after Apple yanked the flawed iOS 8.0.1, it began offering the substitute to customers.

"Fixes an issue in iOS 8.0.1 that impacted cellular network connectivity and Touch ID on iPhone 6 and iPhone 6 Plus," the note accompanying iOS 8.0.2 stated.

Computerworld confirmed that the iOS 8.0.2 update installed on both the newest iPhones as well as on older models without problems, and without blocking phone calls on the iPhone 6 and 6 Plus.

According to Apple, iOS 8.0.1 had affected only the newest iPhones, although there were scattered reports -- including a small handful from Computerworld readers -- that they had experienced problems with their iPads after installing Wednesday's update during the narrow 90-minute window that it was available that day.

Customers had blasted Apple for the bungled iOS 8.0.1, wondering how the company had not caught the problem in testing. Some had demanded compensation for their troubles.

iPhone owners who downloaded iOS 8.0.1 while it was available, but did not finish the installation process before Apple pulled the update must first delete it from their devices before they will be able to retrieve 8.0.2. To delete the iOS 8.0.1 download, users must touch the "Settings" icon, then "General," next "Usage," and finally "Manage Storage." Tapping the iOS 8.0.1 item and selecting "Delete" will remove the obsolete update.

OS 8.0.2 can be downloaded over the air from iPhones, iPads, iPad Minis and iPod Touches, or through iTunes. From an iPhone, for instance, users must touch the "Settings" icon, then "General" button on the resulting screen. Tapping "Software Update" will kick off the update process.
